CLngInt

Converts a number or string to a 64-bit LongInt, rounding to the nearest.

Syntax

Declare Function CLngInt ( ByVal expression As datatype ) As LongInt
Type typename
Declare Operator Cast ( ) As LongInt
End Type

Parameters

• expression
• datatype
• typename

Description

The CLngInt function rounds off the decimal part and returns a 64-bit LongInt value. The function does not check for an overflow, and results are undefined for values which are less than -9 223 372 036 854 775 808 or larger than 223 372 036 854 775 807.

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

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

Return Value

A LongInt value.

Remarks

Usage

result = CLngInt( numeric expression )

result = CLngInt( string expression )

result = CLngInt( user defined type )
