Math expressions calculator with custom operators, functions and variables

This package no longer supported! Please use AceCalculator instead!

Install via Composer
--------------------

[](#install-via-composer)

|$ composer require avadim/math-executor

All instructions to install here:

Sample usage
------------

[](#sample-usage)

```
require 'vendor/autoload.php';

$calculator = new \avadim\MathExecutor\MathExecutor();

print $calculator->execute('1 + 2 * (2 - (4+10))^2 + sin(10)');

// cascade execution - variable $_ has result of previous calculation
print $calculator
        ->calc('4+10')
        ->calc('1 + 2 * (2 - $_)^2')
        ->calc('$_ + sin(10)')
        ->getResult();
```

Default operators and functions
-------------------------------

[](#default-operators-and-functions)

Default operators: `+ - * / ^`

Default functions:

- sin
- cos
- tn
- asin
- acos
- atn
- min
- max
- avg

Variables
---------

[](#variables)

Default variables:

```
$pi = 3.14159265359
$e = 2.71828182846

```

You can add own variable to executor:

```
$calculator->setVars([
    'var1' => 0.15,
    'var2' => 0.22
]);

$calculator->execute('$var1 + $var2');
```

Extra operators and functions
-----------------------------

[](#extra-operators-and-functions)

To load extra operators and functions use method `loadExtra()`:

```
$calculator->loadExtra();
```

Extra operators are boolean operators: `<  >= == !=`You can use boolean operators with function `if()`

```
print $calculator->execute('if(100+20+3 > 111, 23, 34)');
```

Custom functions
----------------

[](#custom-functions)

Add custom function to executor:

```
$calculator->addFunction('hypotenuse', function($a, $b) {
    return sqrt($a ** 2 + $b ** 2);
}, 2);

print $calculator->execute('hypotenuse(3,4)');
```

Custom operators
----------------

[](#custom-operators)

Add custom operator to executor:

```
