Bitwise Functions
FLEX Function Reference

bitwise.and

Description

Performs a bitwise AND operation on two integers. Each bit in the result is 1 only if the corresponding bits in both operands are 1.

Syntax

flex.bitwise.and(a, b)

Parameters

Parameter Type Required Description
a number (integer) Yes First operand
b number (integer) Yes Second operand

Returns

Type: number (integer)

The result of the bitwise AND operation.

Examples

Example 1: Basic AND Operation

RETURN flex.bitwise.and(12, 10) AS result

Output:

result
------
8

(Binary: 1100 AND 1010 = 1000 = 8)

Example 2: Checking Permission Flags

WITH 7 AS userPermissions  // 0111 (read=1, write=2, execute=4)
WITH userPermissions, 2 AS writeFlag
RETURN flex.bitwise.and(userPermissions, writeFlag) > 0 AS hasWrite

Example 3: Masking Bits

MATCH (d:Device)
WITH d, flex.bitwise.and(d.flags, 15) AS lowerNibble
RETURN d.id, lowerNibble

Notes

  • Operates on 32-bit signed integers in JavaScript
  • Both operands are converted to integers if needed
  • Commonly used for flag checking and bit masking
