Conversion Functions

You can use conversion functions to convert data from one subtype to another. In addition, the VarType function returns information about how your data is stored within a Variant.

VBScript supports the following commonly used conversion functions:

CBool(vVariant) - Converts an expression to a variant of subtype Boolean

CByte(vVariant) - Converts an expression to a variant of subtype Byte

CCur(vVariant) - Converts an expression to a variant of subtype Currency

CDate(vVariant) - Converts a valid date and time expression to the variant of subtype Date

CDbl(vVariant) - Converts an expression to a variant of subtype Double

CInt(vVariant) - Converts an expression to a variant of subtype Integer

CLng(vVariant) - Converts an expression to a variant of subtype Long

CSng(vVariant) - Converts an expression to a variant of subtype Single

CStr(vVariant) - Converts an expression to a variant of subtype String

Example :

document.writeln("7=" & (7) & " : " & TypeName(7))

document.writeln("CByte(7)=" & (CByte(7)) & " : " _ & TypeName(CByte(7)))

 document.writeln("777=" & (777) & " : " & TypeName(777))

 document.writeln("777777=" & (777777) & " : " & TypeName(777777))

 document.writeln("9.99=" & (9.99) & " : " & TypeName(9.99))

 document.writeln("CSng(9.99)=" & (CSng(9.99)) & " : " & TypeName(CSng(9.99)))

 document.writeln("0.00314159e30=" & (0.00314159e30) & " : " &TypeName(0.00314159e30))

 document.writeln("333.333e200=" & (333.333e200) & " : " & TypeName(333.333e200))

 document.writeln("CCur(9.99)=" & (CCur(9.99)) & " : " & TypeName(CCur(9.99)))

 document.writeln("""Hello""=" & ("Hello") & " : " & TypeName("Hello"))

 document.writeln("TRUE=" & (TRUE) & " : " & TypeName(TRUE))

 document.writeln("#31-Dec-1999#=" & (#31-Dec-1999#) & " : " & TypeName(#31-Dec-1999#))

 document.writeln("Empty=" & (Empty) & " : " & TypeName(Empty))

 document.writeln("Null=" & (Null) & " : " & TypeName(Null))
