Class Float

  • All Implemented Interfaces:
    Serializable, Comparable<Float>


    public final class Float
    extends Number
    implements Comparable<Float>
    The Float class wraps a value of primitive type float in an object. An object of type Float contains a single field whose type is float.

    In addition, this class provides several methods for converting a float to a String and a String to a float, as well as other constants and methods useful when dealing with a float.

    • Method Detail

      • toString

        public static String toString(float f)
        Returns a string representation of the float argument. All characters mentioned below are ASCII characters.
        • If the argument is NaN, the result is the string "NaN".
        • Otherwise, the result is a string that represents the sign and magnitude (absolute value) of the argument. If the sign is negative, the first character of the result is '-' ('\u002D'); if the sign is positive, no sign character appears in the result. As for the magnitude m:
          • If m is infinity, it is represented by the characters "Infinity"; thus, positive infinity produces the result "Infinity" and negative infinity produces the result "-Infinity".
          • If m is zero, it is represented by the characters "0.0"; thus, negative zero produces the result "-0.0" and positive zero produces the result "0.0".
          • If m is greater than or equal to 10-3 but less than 107, then it is represented as the integer part of m, in decimal form with no leading zeroes, followed by '.' ('\u002E'), followed by one or more decimal digits representing the fractional part of m.
          • If m is less than 10-3 or greater than or equal to 107, then it is represented in so-called "computerized scientific notation." Let n be the unique integer such that 10n m < 10n+1; then let a be the mathematically exact quotient of m and 10n so that 1 ≤ a < 10. The magnitude is then represented as the integer part of a, as a single decimal digit, followed by '.' ('\u002E'), followed by decimal digits representing the fractional part of a, followed by the letter 'E' ('\u0045'), followed by a representation of n as a decimal integer, as produced by the method Integer.toString(int).
        How many digits must be printed for the fractional part of m or a? There must be at least one digit to represent the fractional part, and beyond that as many, but only as many, more digits as are needed to uniquely distinguish the argument value from adjacent values of type float. That is, suppose that x is the exact mathematical value represented by the decimal representation produced by this method for a finite nonzero argument f. Then f must be the float value nearest to x; or, if two float values are equally close to x, then f must be one of them and the least significant bit of the significand of f must be 0.

        To create localized string representations of a floating-point value, use subclasses of NumberFormat.

        Parameters:
        f - the float to be converted.
        Returns:
        a string representation of the argument.
      • toHexString

        public static String toHexString(float f)
        Returns a hexadecimal string representation of the float argument. All characters mentioned below are ASCII characters.
        • If the argument is NaN, the result is the string "NaN".
        • Otherwise, the result is a string that represents the sign and magnitude (absolute value) of the argument. If the sign is negative, the first character of the result is '-' ('\u002D'); if the sign is positive, no sign character appears in the result. As for the magnitude m:
          • If m is infinity, it is represented by the string "Infinity"; thus, positive infinity produces the result "Infinity" and negative infinity produces the result "-Infinity".
          • If m is zero, it is represented by the string "0x0.0p0"; thus, negative zero produces the result "-0x0.0p0" and positive zero produces the result "0x0.0p0".
          • If m is a float value with a normalized representation, substrings are used to represent the significand and exponent fields. The significand is represented by the characters "0x1." followed by a lowercase hexadecimal representation of the rest of the significand as a fraction. Trailing zeros in the hexadecimal representation are removed unless all the digits are zero, in which case a single zero is used. Next, the exponent is represented by "p" followed by a decimal string of the unbiased exponent as if produced by a call to Integer.toString on the exponent value.
          • If m is a float value with a subnormal representation, the significand is represented by the characters "0x0." followed by a hexadecimal representation of the rest of the significand as a fraction. Trailing zeros in the hexadecimal representation are removed. Next, the exponent is represented by "p-126". Note that there must be at least one nonzero digit in a subnormal significand.

      • valueOf

        public static Float valueOf(String s)
                             throws NumberFormatException
        Returns a Float object holding the float value represented by the argument string s.

        If s is null, then a NullPointerException is thrown.

        Leading and trailing whitespace characters in s are ignored. Whitespace is removed as if by the String.trim() method; that is, both ASCII space and control characters are removed. The rest of s should constitute a FloatValue as described by the lexical syntax rules:

        FloatValue:
        Signopt NaN
        Signopt Infinity
        Signopt FloatingPointLiteral
        Signopt HexFloatingPointLiteral
        SignedInteger
        HexFloatingPointLiteral:
        HexSignificand BinaryExponent FloatTypeSuffixopt
        HexSignificand:
        HexNumeral
        HexNumeral .
        0x HexDigitsopt . HexDigits
        0X HexDigitsopt . HexDigits
        BinaryExponent:
        BinaryExponentIndicator SignedInteger
        BinaryExponentIndicator:
        p
        P
        where Sign, FloatingPointLiteral, HexNumeral, HexDigits, SignedInteger and FloatTypeSuffix are as defined in the lexical structure sections of The Java™ Language Specification, except that underscores are not accepted between digits. If s does not have the form of a FloatValue, then a NumberFormatException is thrown. Otherwise, s is regarded as representing an exact decimal value in the usual "computerized scientific notation" or as an exact hexadecimal value; this exact numerical value is then conceptually converted to an "infinitely precise" binary value that is then rounded to type float by the usual round-to-nearest rule of IEEE 754 floating-point arithmetic, which includes preserving the sign of a zero value. Note that the round-to-nearest rule also implies overflow and underflow behaviour; if the exact value of s is large enough in magnitude (greater than or equal to (MAX_VALUE + ulp(MAX_VALUE)/2), rounding to float will result in an infinity and if the exact value of s is small enough in magnitude (less than or equal to MIN_VALUE/2), rounding to float will result in a zero. Finally, after rounding a Float object representing this float value is returned.

        To interpret localized string representations of a floating-point value, use subclasses of NumberFormat.

        Note that trailing format specifiers, specifiers that determine the type of a floating-point literal (1.0f is a float value; 1.0d is a double value), do not influence the results of this method. In other words, the numerical value of the input string is converted directly to the target floating-point type. In general, the two-step sequence of conversions, string to double followed by double to float, is not equivalent to converting a string directly to float. For example, if first converted to an intermediate double and then to float, the string
        "1.00000017881393421514957253748434595763683319091796875001d"
        results in the float value 1.0000002f; if the string is converted directly to float, 1.0000001f results.

        To avoid calling this method on an invalid string and having a NumberFormatException be thrown, the documentation for Double.valueOf lists a regular expression which can be used to screen the input.

        Parameters:
        s - the string to be parsed.
        Returns:
        a Float object holding the value represented by the String argument.
        Throws:
        NumberFormatException - if the string does not contain a parsable number.
      • valueOf

        public static Float valueOf(float f)
        Returns a Float instance representing the specified float value. If a new Float instance is not required, this method should generally be used in preference to the constructor Float(float), as this method is likely to yield significantly better space and time performance by caching frequently requested values.
        Parameters:
        f - a float value.
        Returns:
        a Float instance representing f.

        Note that in most cases, for two instances of class Float, f1 and f2, the value of f1.equals(f2) is true if and only if

           f1.floatValue() == f2.floatValue()
         

        also has the value true. However, there are two exceptions:

        • If f1 and f2 both represent Float.NaN, then the equals method returns true, even though Float.NaN==Float.NaN has the value false.
        • If f1 represents +0.0f while f2 represents -0.0f, or vice versa, the equal test has the value false, even though 0.0f==-0.0f has the value true.
        This definition allows hash tables to operate properly.
        Overrides:
        equals in class Object
        Parameters:
        obj - the object to be compared
        Returns:
        true if the objects are the same; false otherwise.

      • floatToIntBits

        public static int floatToIntBits(float value)
        Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout.

        Bit 31 (the bit that is selected by the mask 0x80000000) represents the sign of the floating-point number. Bits 30-23 (the bits that are selected by the mask 0x7f800000) represent the exponent. Bits 22-0 (the bits that are selected by the mask 0x007fffff) represent the significand (sometimes called the mantissa) of the floating-point number.

        If the argument is positive infinity, the result is 0x7f800000.

        If the argument is negative infinity, the result is 0xff800000.

        If the argument is NaN, the result is 0x7fc00000.

        In all cases, the result is an integer that, when given to the intBitsToFloat(int) method, will produce a floating-point value the same as the argument to floatToIntBits (except all NaN values are collapsed to a single "canonical" NaN value).

        Parameters:
        value - a floating-point number.
        Returns:
        the bits that represent the floating-point number.
      • floatToRawIntBits

        public static int floatToRawIntBits(float value)
        Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout, preserving Not-a-Number (NaN) values.

        Bit 31 (the bit that is selected by the mask 0x80000000) represents the sign of the floating-point number. Bits 30-23 (the bits that are selected by the mask 0x7f800000) represent the exponent. Bits 22-0 (the bits that are selected by the mask 0x007fffff) represent the significand (sometimes called the mantissa) of the floating-point number.

        If the argument is positive infinity, the result is 0x7f800000.

        If the argument is negative infinity, the result is 0xff800000.

        If the argument is NaN, the result is the integer representing the actual NaN value. Unlike the floatToIntBits method, floatToRawIntBits does not collapse all the bit patterns encoding a NaN to a single "canonical" NaN value.

        In all cases, the result is an integer that, when given to the intBitsToFloat(int) method, will produce a floating-point value the same as the argument to floatToRawIntBits.

        Parameters:
        value - a floating-point number.
        Returns:
        the bits that represent the floating-point number.

      • intBitsToFloat

        public static float intBitsToFloat(int bits)
        Returns the float value corresponding to a given bit representation. The argument is considered to be a representation of a floating-point value according to the IEEE 754 floating-point "single format" bit layout.

        If the argument is 0x7f800000, the result is positive infinity.

        If the argument is 0xff800000, the result is negative infinity.

        If the argument is any value in the range 0x7f800001 through 0x7fffffff or in the range 0xff800001 through 0xffffffff, the result is a NaN. No IEEE 754 floating-point operation provided by Java can distinguish between two NaN values of the same type with different bit patterns. Distinct values of NaN are only distinguishable by use of the Float.floatToRawIntBits method.

        In all other cases, let s, e, and m be three values that can be computed from the argument:

        
         int s = ((bits >> 31) == 0) ? 1 : -1;
         int e = ((bits >> 23) & 0xff);
         int m = (e == 0) ?
                         (bits & 0x7fffff) << 1 :
                         (bits & 0x7fffff) | 0x800000;
         
        Then the floating-point result equals the value of the mathematical expression s·m·2e-150.

        Note that this method may not be able to return a float NaN with exactly same bit pattern as the int argument. IEEE 754 distinguishes between two kinds of NaNs, quiet NaNs and signaling NaNs. The differences between the two kinds of NaN are generally not visible in Java. Arithmetic operations on signaling NaNs turn them into quiet NaNs with a different, but often similar, bit pattern. However, on some processors merely copying a signaling NaN also performs that conversion. In particular, copying a signaling NaN to return it to the calling method may perform this conversion. So intBitsToFloat may not be able to return a float with a signaling NaN bit pattern. Consequently, for some int values, floatToRawIntBits(intBitsToFloat(start)) may not equal start. Moreover, which particular bit patterns represent signaling NaNs is platform dependent; although all NaN bit patterns, quiet or signaling, must be in the NaN range identified above.

        Parameters:
        bits - an integer.
        Returns:
        the float floating-point value with the same bit pattern.
      • compareTo

        public int compareTo(Float anotherFloat)
        Compares two Float objects numerically. There are two ways in which comparisons performed by this method differ from those performed by the Java language numerical comparison operators (<, <=, ==, >=, >) when applied to primitive float values:
        • Float.NaN is considered by this method to be equal to itself and greater than all other float values (including Float.POSITIVE_INFINITY).
        • 0.0f is considered by this method to be greater than -0.0f.
        This ensures that the natural ordering of Float objects imposed by this method is consistent with equals.
        Specified by:
        compareTo in interface Comparable<Float>
        Parameters:
        anotherFloat - the Float to be compared.
        Returns:
        the value 0 if anotherFloat is numerically equal to this Float; a value less than 0 if this Float is numerically less than anotherFloat; and a value greater than 0 if this Float is numerically greater than anotherFloat.
        Since:

        Compares the two specified float values. The sign of the integer value returned is the same as that of the integer that would be returned by the call:
            new Float(f1).compareTo(new Float(f2))
         
        Parameters:
        f1 - the first float to compare.

        Returns:
        the value 0 if f1 is numerically equal to f2; a value less than 0 if f1 is numerically less than f2; and a value greater than 0 if f1 is numerically greater than f2.
