In c++, can the modulo operator (%) be applied directly to floating -point numbers? such as float or double?

Question

cout << 5.0 % 2;
If the compiler produces error, is there any way to do it?
Can anyone please clarify?

Answer 1

No because it doesn't make sense in real world mathematics.
Real numbers can go on infinitely, so there isn't a remainder.

fmod exists, but it may not give what you expect
