PriceTidy

PriceTidy is a PHP library for seamless price rounding and adjustment using various rounding strategies.

Installation

To install PriceTidy, you can use Composer:

composer require dnkmdg/price-tidy

Usage

Here's a basic example of how to use PriceTidy:

use Dnkmdg\PriceTidy\PriceTidy;
use Dnkmdg\PriceTidy\Strategies\RoundUpToNearestIntegerStrategy;

$priceTidy = new PriceTidy(10.5, 1.25, new RoundUpToNearestIntegerStrategy());
echo $priceTidy->priceIncVat; // Output: 14

Rounding Strategies

PriceTidy supports multiple rounding strategies:

• RoundUpToNearestIntegerStrategy: Rounds up to the nearest integer.
• RoundUpToNearestNineStrategy: Rounds up to the nearest nine.
• RoundUpToNearestTenStrategy: Rounds up to the nearest ten.
• RoundUpToNearestHundredStrategy: Rounds up to the nearest hundred.
• EuroStrategy: Example of a custom rounding strategy.

Example

use Dnkmdg\PriceTidy\PriceTidy;
use Dnkmdg\PriceTidy\Strategies\RoundUpToNearestTenStrategy;

$priceTidy = new PriceTidy(10.5, 1.25, new RoundUpToNearestTenStrategy());
echo $priceTidy->priceIncVat; // Output: 20

Custom Rounding Strategy

You can create your own custom rounding strategy by extending the RoundingStrategy abstract class and implementing the round method.

Here's an example of a custom rounding strategy that rounds to the nearest five:

namespace Dnkmdg\PriceTidy\Strategies;

class RoundToNearestFiveStrategy extends RoundingStrategy
{
    public function round(float $value): float
    {
        return round($value / 5) * 5;
    }
}

To use this custom strategy with PriceTidy:

use Dnkmdg\PriceTidy\PriceTidy;
use Dnkmdg\PriceTidy\Strategies\RoundToNearestFiveStrategy;

$priceTidy = new PriceTidy(10.5, 1.25, new RoundToNearestFiveStrategy());
echo $priceTidy->priceIncVat; // Output will be 15

Running Tests

To run the tests, use PHPUnit:
