FLOAT (M,D)


Description

The FLOAT data type represents a small (single-precision) floating-point number.

Permissible values are:
-3.402823466E+38 to -1.175494351E-38, 0, and 1.175494351E-38 to 3.402823466E+38.

A single-precision floating-point number is accurate to approximately 7 decimal places.

This data type has the form:

FLOAT[(M[,D])] [UNSIGNED]
  [ZEROFILL]

In this form, M is the total number of digits and D is the number of digits following the decimal point. If M and D are omitted, values are stored to the limits permitted by the hardware.

Options Description
UNSIGNED If specified, disallows negative values.
ZEROFILL Specifies that the default padding of spaces is replaced with zeros.

If you specify ZEROFILL for a numeric column, MySQL automatically adds the UNSIGNED attribute to the column.
