CLng

Converts numeric or string expression to Long

Syntax
   Declare Function CLng ( ByVal expression As datatype ) As Long

   Type typename
      Declare Operator Cast ( ) As Long
   End Type

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
   datatype
      any numeric, string, or pointer data type
   typename
      a user defined type

Return Value
   A Long value.

Description
   The CLng function rounds off the decimal part and returns a 32-bit Long 
   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 
   147 483 647.

   The name can be explained as 'Convert to LoNG'.

   If the argument is a string expression, it is converted to numeric by 
   using ValInt.

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
