README

A package for handling numbers in Laravel.

Installation

You can install the package via composer:

composer require worksome/number

Usage

use Worksome\Number\Number;

$number = Number::of(100);

$number->mul(Number::of(5));

echo $number; // 500

Casting

This package allows you to easily cast attributes on your Eloquent models to number types.

use Illuminate\Database\Eloquent\Model;
use Worksome\Number\Casts\NumberFromCents;
use Worksome\Number\Casts\NumberFromDecimal;
use Worksome\Number\MonetaryAmount;
use Worksome\Number\Percentage;
use Worksome\Number\Number;

class Product extends Model
{
    protected $casts = [
        'a' => NumberFromCents::class,
        'b' => NumberFromDecimal::class,
        'c' => NumberFromDecimal::using(2, MonetaryAmount::class), // Cast to a specialised Number-class
        'd' => NumberFromDecimal::using(2, Percentage::class), // Cast to a specialised Number-class
        'e' => NumberFromDecimal::using(3), // Three decimal places - default is 2
    ];
}

Available Number Types

The following Number types are available out of the box:

• Number - The base number type, with two decimal places. Can be configured to use a different default scale.
• MonetaryAmount - A number type for handling monetary amounts. Always uses two decimal places. Rounds automatically in all operations.
• Percentage - A number type for handling percentages. Makes it clear that the number represents a percentage, not an amount. Adds % on to string representations.

GraphQL

This package also provides GraphQL scalar types for the WebOnyx GraphQL PHP package / Lighthouse.

These will be auto-registered for Lighthouse by Worksome\Number\Providers\NumberServiceProvider. However, if you want to do this manually, they can be registered in the type registry using:

// In Lighthouse (https://lighthouse-php.com)
$typeRegistry->register(new \Worksome\Number\GraphQL\Scalars\DecimalTwoType());
$typeRegistry->register(new \Worksome\Number\GraphQL\Scalars\PercentageType());
$typeRegistry->register(new \Worksome\Number\GraphQL\Scalars\StrictPercentageType());
