Data Types

Data Types

VBScript has only one data type called a variant. A Variant is a special data type that can contain different kinds of information, depending on how it is used.

It is important to note that VBScript will automatically change the data type of a variable as soon as the variable is assigned.

Note: All functions in VBScript return the data type Variant.

The following table lists the data types a Variant can contain:

Data Type Description
Empty Variant is uninitialized. Value is 0 for numeric variables or a zero-length string ("") for string variables.
Null Variant intentionally contains no valid data.
Boolean Contains either True or False.
Byte Contains integer in the range 0 to 255.
Integer Contains integer in the range -32,768 to 32,767.
Currency -922,337,203,685,477.5808 to 922,337,203,685,477.5807.
Long Contains integer in the range -2,147,483,648 to 2,147,483,647.
Single Contains a single-precision, floating-point number in the range -3.402823E38 to -1.401298E-45 for negative values; 1.401298E-45 to 3.402823E38 for positive values.
Double Contains a double-precision, floating-point number in the range -1.79769313486232E308 to -4.94065645841247E-324 for negative values; 4.94065645841247E-324 to 1.79769313486232E308 for positive values.
Date (Time) Contains a number that represents a date between January 1, 100 to December 31, 9999.
String Contains a variable-length string that can be up to approximately 2 billion characters in length.
Object Contains an object.
Error Contains an error number.

Identifying Variable Types

The data type of a variable can be examined by using either of two VBScript functions:

  • TypeName - returns the name of the data type
  • VarType - returns the VBScript number representing the data type

The following example demonstrates the changing data type:

Dim v
'Returns Empty

v = 1
'Returns Integer

v = 1234567
'Returns Long

v = 123.45
'Returns Double

v = "Hello from VBScript"
'Returns String
