Bitwise OR (|) Expression

Summary

Evaluate with a logical inclusive OR operation.

Syntax

expression1 | expression2

Parameters

expression1: Any legal Boolean or numeric expression.
expression2: Any legal Boolean or numeric expression.

Description

For numeric and Boolean expressions, the | operator computes the values of the operands, converts them to equal-length binary representations, performs a logical inclusive OR operation on them, and returns the evaluated result. For example, the decimal (base 10) number 0 (zero) may be converted to the binary form 0000 and the number 1 (one) may be converted to 0001. The bitwise OR operation will compare each bit. If both bits are 0 (zero), the resulting bit is 0 (zero); otherwise, the resulting bit is 1 (one).

For example, here is an illustration of the evaluation of the expression 0 | 1:

  0000 (0)
  0001 (1)
  ----
= 0001 (1)

Here is an illustration for the evaluation of the expression 3 | 5:

  0011 (3)
  0101 (5)
  ----
= 0111 (7)

Differences from JavaScript

Logical OR operations are not limited to 32-bit integers in JS++. ^{Unimplemented} In JavaScript, the logical OR operation is limited to signed 32-bit integers.

Examples

Basic Usage

import System;
 
Console.log(0 | 0); // 0
Console.log(0 | 1); // 1
Console.log(1 | 5); // 5
