simple-math-eval-calc

A simple, small, and alternative code to replace javascript native eval() function.

Purpose

Accept mathematical expression (numerical expressions) based on a string only.

Operations

It currently accepts:

Addition
Subtraction
Multiplication
Division
Exponentation

Usage

Download the release file.
Include src/calc.js by adding it as a script in your HTML file.
Use it!

Example

Eval(" 1 + 1"); //returns 2
Eval("10 - 5"); //returns 5
Eval("6 * 2"); //returns 12
Eval("14 / 7"); //returns 2
Eval("2 ^ 2"); //returns 4

How it works

The Eval() function accepts a string

It is then parsed by the parser,
then it will be arrange by the transformer,
and lastly it will be generated,
and the expression is evaluated.
Returns the output as a string.

What type of algorithm or notation does it use?

The Eval() uses the Shunting Yard Algorithm and Reverse Polish Notation.
