Package Exports

mathops

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mathops) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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"
