// Let's say we have a given angle of 765.2 degrees. If we want to
// normalize that, it means that we have to subtract X * 360 degrees
// to get the correct angle. How could we do that? A good method is
// to use the modulo function. But if we write "765.2 % 360", it won't
// work, because the standard modulo function works only with integer
-// values. In the C library "math" there is a function called "fmod".
-// The "f" stands for floating and means that we can solve modulo for
-// real numbers. With this function it should be possible to normalize
