mathops

This module contains functions that implement the basic operators of Javascript: the mathematical operators (+, -, ...), the arithmetic operators (++, --, ...), the bitwise operators (^, ~, ...), the logical operators (&&, ||, ...), and the comparison operators (>, <, ...). It is similar to the operator library from Python.

Installation

To install mathops into your project, first cd to your project directory; then type the following.

npm install mathops --save

Use

Simply require mathops in your project and call any of its functions.

var operator = require('mathops');

console.log(operator.add(5, 3));

API

This is a list of all the functions supported by mathops and their base operator equivalents.

Base Mathematical Operators

• add(x, y): "x + y"
• sub(x, y): "x - y"
• mul(x, y): "x * y"
• div(x, y): "x / y"

Arithmetic Operators

• mod(x, y): "x % y"
• inc(x): "++x"
• dec(x): "--x"
• neg(x): "-x"

Bitwise Operators

• and(x, y): "x & y"
• or(x, y): "x | y"
• xor(x, y): "x ^ y"
• not(x): "~x"
• lshift(x, y): "x << y"
• rshift(x, y): "x >> y"
• zrshift(x, y): "x >>> y"

Logical Operators

• land(x, y): "x && y"
• lor(x, y): "x || y"
• lnot(x): "!x"

Comparison Operators

• eq(x, y): "x == y"
• neq(x, y): "x != y"
• steq(x, y): "x === y"
• stneq(x, y): "x !== y"
• gt(x, y): "x > y"
• ge(x, y): "x >= y"
• lt(x, y): "x < y"
• le(x, y): "x <= y"

Testing

To run the included unit tests, type the following command.
