This library includes some tools for math operations.
Here's an example of rounding problems solved by this lib:
$price = new Number('3.99');
$price->divide('1.2');
echo $price->getNumber(); // 3.33
$price->multiply('1.2');
echo $price->getNumber(); // 3.99, where most of time libs returns 4.00This tool computes the GCD of two numbers.
echo GCD::getGCD(10,5); // 5
echo GCD::getGCD(10,10); // 10
echo GCD::getGCD(20,10); // 10
echo GCD::getGCD(11,10); // 1
