    You can use, it's not just overloaded with %. Check fmod() : http://www.cplusplus.com/reference/clibrary/cmath/fmod/

    Maybe it's because cmath is a external lib. C/C++ itself does not allow it, but, on the other hand, both are minimal languages: they don't have an I/O built-in. Well, anyway, hope I helped you, cmath is a nice lib :-)

    It kind of makes sense to me that floating point numbers are not supported by the modulo operation. The modulo operation gives you the remainder after an integer division (so 12 % 10 = 2). But what would be the remainder of a floating point division? Take e.g. 10 / 2.1 = 4.762. Apart from rounding errors, a floating point number is always fully divisible, so it won't have a remainder. What would be the point of a modulo operation without a remainder?
