fmod() in PHP is the worst !”#¤%&/()= function ever!

I hate floating point artithmetic and I really hate fmod() in PHP. It’s useless.

fmod — Returns the floating point remainder (modulo) of the division of the arguments

If you calculate 36 modulo 7.2? What do you get? Zero, yes. 7.2*5=36. No remainder!

What if you use fmod in PHP?

$ php -r 'echo fmod(36,7.2);'
7.2

WTF? Excuse me? Is that the result from IEEE 754 hell, a parallel universe, or what?

Now I’m betting on the function below. I hope it won’t let me down.

function modulo($n,$b) { return $n-$b*floor($n/$b); }
