Return Types

The function name determines the return type as shown in the following:

Function	Return Type	Range for expression argument
CBool	Boolean	Any valid string or numeric expression.
CByte	Byte	0 to 255.
CCur	Currency	-922,337,203,685,477.5808 to 922,337,203,685,477.5807.
CDate	Date	Any valid date expression.
CDbl	Double	-1.79769313486231E308 to -4.94065645841247E-324 for negative values; 4.94065645841247E-324 to 1.79769313486232E308 for positive values.
CDec	Decimal	+/-79,228,162,514,264,337,593,543,950,335 for zero-scaled numbers, that is, numbers with no decimal places. For numbers with 28 decimal places, the range is +/-7.9228162514264337593543950335. The smallest possible non-zero number is 0.0000000000000000000000000001.

CLngLng	LongLong	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807; fractions are rounded. (Valid on 64-bit platforms only.)
CLngPtr	LongPtr	-2,147,483,648 to 2,147,483,647 on 32-bit systems, -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 on 64-bit systems; fractions are rounded for 32-bit and 64-bit systems.
CSng	Single	-3.402823E38 to -1.401298E-45 for negative values; 1.401298E-45 to 3.402823E38 for positive values.
CStr	String	Returns for CStr depend on the expression argument.
CVar	Variant	Same range as Double for numerics. Same range as String for non-numerics.
