SimpleMath
==========

[](#simplemath)

Simple math expression evaluator.

Please note that in most cases it's better to use [Symfony ExpressionLanguage Component](https://packagist.org/packages/symfony/expression-language) instead. It performs better and provides more features.

This repository will probably not receive any updates in future.

Features
--------

[](#features)

- Supports basic arithmetic operations `+`, `-`, `*`, `/`, `%`
- Supports parenthesis
- Supports right associative ternary operator
- Supports comparison operators `==`, `!=`, `>`, `=`, `evaluate('1 + 2');

// Evaluate expression with PHP style variable
$math->registerVariable('$a', 4);
$value = $math->evaluate('$a + 1');

// Evaluate expression with variable
$math->registerVariable('n', 4);
$value = $math->evaluate('n + 1');

// Calculate same expression with different values
$math = new SimpleMath\Math();

$math->parse('n + 1');

$math->registerVariable('n', 10);
$value = $math->run();

$math->registerVariable('n', 100);
$value = $math->run();
```
