Converts numeric or string expression to Single precision floating point

Syntax

declare function Csng ( byval expression as datatype ) as single

Type typename

declare operator cast ( ) as single

End Type

Usage

result = Csng( numeric expression )
result = Csng( string expression )
result = Csng( user defined type )

Parameters

expression

a numeric, string, or pointer expression to cast to a Single value

datatype

any numeric, string, or pointer data type

typename

a user defined type

Return Value

A Single precision value.

Description

The Csng function returns a 32-bit Single value. The function does not check for an overflow, so be sure not to pass a value outside the representable range of the Single data type. The name can be explained as 'Convert to SiNGle'.

If the argument to Csng is a string expression, it is first converted to numeric by using Val.

Examples

start GeSHi

' Using the CSNG function to convert a numeric value

'Create an SINGLE variable
Dim numeric_value As Single

'Convert a numeric value
numeric_value = CSng(-12345.123)

'Print the result, should return -12345.123
Print numeric_value
Sleep

end GeSHi

Differences from QB
