Converts numeric or string expression to KeyPgLong Long having the same size as KeyPgSizeof Sizeof(KeyPgAny Any KeyPgPtr Ptr)

result = Clng( numeric expression )
result = Clng( string expression )
result = Clng( user defined type )

a numeric, string, or pointer expression to cast to a KeyPgLong Long value
any numeric, string, or pointer data type
a user defined type

Return Value:
A KeyPgLong Long value.

The Clng function rounds off the decimal part and returns a 32-bit KeyPgInteger Integer or 64-bit KeyPgLongint Longint value. The function does not check for an overflow, and results are undefined for values which are less than -2 147 483 648 or larger than 2 147 483 648.
The name can be explained as 'Convert to LoNG'.
If the argument is a string expression, it is converted to numeric by using KeyPgValint Valint or KeyPgVallng Vallng.
Long has the same size as KeyPgSizeof Sizeof(KeyPgAny Any KeyPgPtr Ptr).


' 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
