Lib Money
=========

[](#lib-money)

[![Build Status](https://camo.githubusercontent.com/2fabfce7b6d2a57ebcfa13ff5c54e58aaba6aecd0a38535e8c0af47c55cb6111/687474703a2f2f63692e61736564696b2e636f6d2f6275696c645374617475732f69636f6e3f6a6f623d6d6f6e65792d62756e646c65)](http://ci.asedik.com/job/money-bundle/)

Overview
--------

[](#overview)

Symfony2 Bundle wrapping common Money and Currency related needs such as integer-based math, currency codes, and money conversion.

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

[](#installation)

Add the package to your composer.json file:

```
{
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/matmar10/lib-money"
        }
    ],
    "require": {
        "matmar10/lib-money": "dev-master"
    }
}

```

Creating Objects
----------------

[](#creating-objects)

Currencies are identified by a currency code and have a calculation and display precision:

```
$eur = new Currency('EUR', 2, 2);

$euros = new Money($eur);
$euros->setAmountFloat(1.99);
```

Basic Math
----------

[](#basic-math)

The Money object wraps all basic math functions using underlying integer math to avoid the (problems with floating point math)\[\].

All amounts are stored as integer values internally using the calculation precision as the scale.

```
// must use a valid iso4217 currency code
// with the exception of BTC for Bitcoin, as specified in the override configuration
$usd = new Currency('USD', 5, 2);

$usdAmount1 = new Money($usd);
$usdAmount1->setAmountFloat(1.2345);

$usdAmount2 = new Money($usd);
$usdAmount2->setAmountFloat(1.2345);

$usdAmount1->isEqual($usdAmount2); // true

$resultAmount1 = $usdAmount1->add($usdAmount2);
echo $resultAmount1->getAmountDisplay(); // 2.47

$resultAmount2 = $usdAmount1->subtract($usdAmount2);
echo $resultAmount2->getAmountFloat(); // 0

$resultAmount3 = $usdAmount1->multiply(3);
echo $resultAmount3->getAmountFloat(); // 3.7035
echo $resultAmount3->getAmountDisplay(); // 3.70

$resultAmount4 = $usdAmount1->divide(2);
echo $resultAmount3->getAmountFloat(); // 0.61725
echo $resultAmount3->getAmountDisplay(); // 0.62
```

Dealing with Fractional Cents
-----------------------------

[](#dealing-with-fractional-cents)

How do you divide $10 evenly amongst three people? In reality, you can't divide fractional cents.

Really, you want to end up with three *equal*-ish shares:

- $3.34
- $3.33
- $3.33

```
$eurAmount = new Money(new Currency('EUR', 2, 2));
$eurAmount->setAmountFloat(10);

// split the 10 euros into three equal parts using euro cents as the smallest unit
$shares = $eurAmount->allocate(array(1, 1, 1), 2);

$shares[0]->getAmountFloat(); // 3.34
$shares[1]->getAmountFloat(); // 3.33
$shares[2]->getAmountFloat(); // 3.33
```

Converting Between Currencies
-----------------------------

[](#converting-between-currencies)

Use the `CurrencyPair` object to convert between disparate currencies using an exchange rate:

Note that the rate works bi-directionally:

```
$gbp = new Currency('GBP', 2, 2);
$usd = new Currency('USD', 2, 2);

$gbpAmount = new Money($gbp);
$gbpAmount->setAmountFloat(10);

// 1 GBP = 1.5 USD
$gbpToUsd = new CurrencyPair($gbp, $usd, 1.5);

$usdAmount = $gbpToUsd->convert($gbpAmount);
echo $usdAmount->getDisplay(); // 15.00

$gbpAmount2 = $gbpToUsd->convert($usdAmount);
echo $gbpAmount2->getDisplay(); // 10.00
```
