CULng
Converts numeric or string expression to `Ulong` having the same size as `SizeOf(Any Ptr)`
Syntax
`
Declare Function CULng ( ByVal expression As datatype ) As Ulong
Type typename
Declare Operator Cast ( ) As Ulong
End Type
`
Usage
`
result = CULng( numeric expression )
result = CULng( string expression )
result = CULng( user defined type )
`
Parameters
`expression`
a numeric, string, or pointer expression to cast to a `Ulong` value
`datatype`
any numeric, string, or pointer data type
`typename`
a user defined type
Return Value
A `Ulong` value.
Description
The `CULng` function rounds off the decimal part and returns a 32 bit `UInteger` or 64 bit `ULongInt` value. The function does not check for an overflow. The name can be explained as 'Convert to Unsigned LoNG'.
If the argument is a string expression, it is converted to numeric by using `ValUInt` or `ValULng`.
`Ulong` has the same size as `SizeOf(Any Ptr)`.
Example
`
' Using the CULNG function to convert a numeric value
'Create an UNSIGNED LONG variable
Dim numeric_value As ULONG
'Convert a numeric value
numeric_value = CULng(300.23)
'Print the result = 300
Print numeric_value
Sleep
