One of these values is exact, and one of these raises FE_INEXACT.
Does it work for 29° and 31° as well? What’s so special about 30°?
Really? This is high school trig.
For units of degree, mathematically sin(30) = 1/2, exactly!.
sin(30+n*360) = 1/2 is also exact.
What’s so special about 30°? Does that extend to 29° and 31° as well?
