Floating point values represent intervals,
This is mathematically wrong. The basic concept is that the calculations domain as given by floating point numbers is used to *model* the real number calculus. Certain constrains apply of course. But there isn't any concept of representation here. Just a mapping.
and when the interval size is way bigger than 2pi any value in [-1,1] is a perfectably acceptable answer for sin or cos.
