Number for Laravel

This package provides a number class that can be used to represent numbers.

All operations are done using bcmath which means that arbitrary precision is supported.

Installation

composer require utecca/number

Usage

// Init via constructor
new Number(123.456);

// Init via static method
Number::of('123.45');

// Force a certain number of decimals
Number::of('123.45', 1); // Will return 123.5

Laravel casting

You can have models cast to Number by adding the following to your model:

protected $casts = [
    // Amount with two decimals (usually used for monetary values) 
    'amount' => Utecca\Number\Casts\NumberFromDecimal::class,
    // Amount with a custom number of decimals
    'quantity' => Utecca\Number\Casts\NumberFromDecimal::class . ':4'),
];

Operations

When doing operations, you always have the option to specify the number of decimals to use.

If not specified, the max number of decimals will be taken from the first operand's max.

// Addition
$number->add(100);

// Subtraction
$number->sub(100);

// Multiplication
$number->mul(100);
