CULng
Converts numeric or string expression to Ulong having the same size as SizeOf(Any Ptr)
result = CULng( numeric expression )
result = CULng( string expression )
result = CULng( user defined type )
expression
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).

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
'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
