CLngPtr

Coerces an expression to a LongPtr.

Syntax: CLngPtr( expression )

expression

required Any valid string or numeric expression. The acceptable range is -2,147,483,648 to 2,147,483,647 on 32-bit systems, and -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 on 64-bit systems. Fractions are rounded.

The return type is LongPtr, which is a Long on 32-bit systems and a LongLong on 64-bit systems. If expression is outside the valid range, a run-time error occurs.

When the fractional part is exactly 0.5, CLngPtr always rounds it to the nearest even number. CLngPtr differs from the Fix and Int functions, which truncate, rather than round, the fractional part of a number.

LongPtr is intended primarily for holding pointer values returned from API calls. See Data Types for details.

Example

This example uses the CLngPtr function to convert an expression to a LongPtr.

Dim num As Variant
num = 1234567890
MsgBox "LongPtr value of " & num & " is " & CLngPtr(num)
