Did you take a high school trigonometry class?
You seem obsessed with that.
So your favourite functions return an exact result for sin 30°. Do they
return an exact result for cos 30° as well?
Nope. For REAL x, COSD(x) returns an exact result for all N >= 0
that satisfies 60+N*360 < 2**23.
Could you give an example of where sind and cosd might be of use in a
piece of numerical software?
