...s with angles that are near multiples of pi. I would posit that 99% of the time, when code asks for sin(x), what it really wants is the sine of (π/Math.PI) times x. The people maintaining Java insist that it's better to have a slow math routine report that the sine of Math.PI is difference between ...
