This number is actually too large for an integer representation in PHP and converting to a float won't get the precision for this number. When doing math that requires huge numbers or accurate precision, it's best to use bc math with strings.

echo bcmul("50000", "1000000000000000000");
// prints "50000000000000000000000"
