x64, Win32

Purpose

To test if the N'th bit of an array is set.

Syntax

INTEGER FUNCTION TEST_BIT@(IA,N)
INTEGER IA(*),N

Description

TEST_BIT@ may be declared as LOGICAL or INTEGER. IA and N can be any INTEGER type.

Return value

TEST_BIT@ returns 1 or 0 (.TRUE. or .FALSE.) according to whether the N'th bit of IA is set or not.
