CLng
Converts numeric or string expression to Long having the same size as SizeOf(Any Ptr)
result = CLng( numeric expression )
result = CLng( string expression )
result = CLng( user defined type )
expression
The CLng function rounds off the decimal part and returns a 32 bit Integer or 64 bit LongInt value. The function does not check for an overflow. The name can be explained as 'Convert to LoNG'.
If the argument is a string expression, it is converted to numeric by using ValInt or ValLng.
Long has the same size as SizeOf(Any Ptr).
Syntax
Usage
result = CLng( numeric expression )
result = CLng( string expression )
result = CLng( user defined type )
Parameters
expression
a numeric, string, or pointer expression to cast to a Long value
datatypeany numeric, string, or pointer data type
typenamea user defined type
Return Value
Description
The CLng function rounds off the decimal part and returns a 32 bit Integer or 64 bit LongInt value. The function does not check for an overflow. The name can be explained as 'Convert to LoNG'.
If the argument is a string expression, it is converted to numeric by using ValInt or ValLng.
Long has the same size as SizeOf(Any Ptr).
Example
' Using the CLNG function to convert a numeric value
'Create an LONG variable
Dim numeric_value As Long
'Convert a numeric value
numeric_value = CLng(-300.23)
'Print the result, should return -300
Print numeric_value
Sleep
'Create an LONG variable
Dim numeric_value As Long
'Convert a numeric value
numeric_value = CLng(-300.23)
'Print the result, should return -300
Print numeric_value
Sleep
Differences from QB
- The string argument was not allowed in QB
- LONG is always 32 bit in QB
