**This project is unit tested against 8.1, and merges are not accepted unless the tests pass.**

Installation
------------

[](#installation)

To install, simply require the package using composer:

```
composer require "samsara/fermat:^2.1"

```

Or include it in your `composer.json` file:

```
{
    "require": {
        "samsara/fermat": "^2.1"
    }
}
```

The project namespace is `Samsara\Fermat\Core\*`. You can view the project on [Packagist](https://packagist.org/packages/samsara/fermat).

### Modules

[](#modules)

Modules are the namespaces outside of `Samsara\Fermat\Core` and provide functionality beyond integer, decimal, and rational numbers.

All of these modules depend on the Core namespace, while some depend on each other to various degrees.

- `Samsara\Fermat\Complex`: Provides complex number functionality. **NOTE:** Imaginary numbers are directly supported by `Core`. Complex numbers are numbers that have both a real part and an imaginary part.
- `Samsara\Fermat\Coordinates`: Provides different coordinate systems that can be used to characterize points and their relations to each other.
- `Samsara\Fermat\Expressions`: Provides various expressions, generally algebraic, that can be handled as a function instead of as a value.
- `Samsara\Fermat\LinearAlgebra`: Provides for math involving matrices and vectors.
- `Samsara\Fermat\Stats`: Provides for math involving statistics *and* probabilities.

Documentation

[](#documentation)

The `Samsara\Fermat\Core\Numbers` factory class provides a way to use the Value classes in Fermat without being as specific as those classes may require. Consider the following code:
