MoneyType is a PHP Experts, Inc., Project meant to keep track of money precisely, even up to millions of dollars.

It is never safe to store money as floats or even integers times one hundred. This project gives you the security you need, so that something like the bug in "Office Space" just won't happen to your enterprise application.

Via Composer

composer require phpexperts/money

use PHPExperts\MoneyType\Money;

$money = new Money(5.22);

$money->add(0.55);
echo "$money\n"; // 5.77

# It keeps precision much much better than mere cents.
$money->subtract(0.0001);
echo "$money\n"; // 5.77
$money->subtract(0.004);
echo "$money\n"; // 5.77
$money->subtract(0.001);
echo "$money\n"; // 5.76

# Actually, to the tenth decimal place.
# So it's Cryptocurrency-ready!
$money->multiply(55.7773);
echo "$money\n"; // 321.55

# But deep down, it stores the true values to many decimals (if you use BCMath).
echo $money->getWithFullPrecision() . "\n"; // 321.5508738395

$money->divide('1.000005');
echo "$money\n"; // 321.55
echo $money->getWithFullPrecision() . "\n"; // 321.5492660931

# You can also compare really large numbers with one another, up to 10 decimal places.
# PHP Experts' MoneyType is cryptocurrency ready! In fact, that's what it was designed for!
$money->compare(321.5492660931);       // 0 = equal
$money->compare(321.549266093009);     // -1 = less
$money->compare(321.5492660931000001); // 1 = more

# Get the object.
print_r($money);

# It is cryptocurrency ready:
# Converts Bitcoins to Satoshis
$btc = '1.55527331';
$satoshis = NumberHelper::convertToCents($btc, 8); // 155527331 (int)
