Chainable math methods for PHP. Designed to make working with math more fluent and easier to read.

### Installation (via Composer)

[](#installation-via-composer)

```
composer require devshed-io/arithmatic
```

### Usage

[](#usage)

Basic usage allows you to chain methods for better readability:

```
Arithmatic
    ::start(5)
    ->add(5)
    ->subtract(7);
    ->divide(2);
    ->multiply(7)
    ->output();
```

The when method will execute the given callback when the first argument given to the method evaluates to true:

```
Arithmatic
    ::start(10)
    ->when(true, fn (Arithmatic $calculation) => $calculation->subtract(5))->output();
```

When also provides a third method that will run when the conditional evaluates to false:

```
Arithmatic
    ::start(10)
    ->when(
        false,
        fn (Arithmatic $calculation) => $calculation->subtract(5),
        fn (Arithmatic $calculation) => $calculation->add(5), // This will run...
    )
    ->output();
```

Arithmatic also provides the underlying run API so you can chain methods with arrays:

```
Arithmatic
    ::make(10)
    ->run([
        'add' => 5,
        'divide' => 2,
        'round'
    ])
    ->output(); // 3
```

N.B. Unless you call `output`, arithmatic will provide an instance of itself. It can be coerced to a string using the `__toString()` or `(string)` methods.
