All variables in VBScript are a data type called Variant.
This means that you do not (and cannot)
explicitly declare the variable type. In fact, with
VBScript you do not need the Dim statement to allocate
storage for a variable. At runtime, the Parser in the
VBScript Scripting Engine determines the Variant
data subtype to be used.
Variant data subtypes Subtype Description
Boolean - Either True or False
Byte - Contains integer in the range 0 to 255
Currency Floating-point number in the range -
922,337,203,685,477.5808 to 922,337,203,685,477.5807
Date(Time)- Contains a number that represents a date
between January 1, 100 to December 31, 9999
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
Empty -Uninitialized Variant
Error -Contains an error number used with runtime errors
Integer -Contains integer in the range -32,768 to 32,767
Long Contains integer in the range -2,147,483,648 to
2,147,483,647
Null -A variant containing no valid data
Object- Contains an object reference
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
String Contains a variable-length string that can be up to
approximately 2 billion characters in length.
The Parsers choice of data subtype will depend on how the
variable is used in a statement or function.
Note that a variable’s subtype can change within a code
segment.
