CSng
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`.
Example
`
' 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
