Syntax
`
Declare Function CULng ( ByVal expression As datatype ) As ULong
Type typename
Declare Operator Cast ( ) As ULong
End Type

result = CULng( numeric expression )
result = CULng( string expression )

`
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 `ULong` 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`.
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
