BITAND function

Syntax

BITAND (expression1, expression2)

Description

Use the BITAND function to perform the bitwise AND comparison of two integers specified by numeric expressions. The bitwise AND operation compares two integers bit by bit. It returns a bit of 1 if both bits are 1; otherwise it returns a bit of 0.

If either expression1 or expression2 evaluates to the null value, null is returned.

Non-integer values are truncated before the operation is performed.

The BITAND operation is performed on a 32-bit twos-complement word.

Note: Differences in hardware architecture can make the use of the high-order bit non-portable.

Example

PRINT BITAND(6,12)
* The binary value of 6  =  0110
* The binary value of 12 =  1100

This results in 0100, and the following output is displayed:
