One thing I don't understand:
cos 0.17098435541865692 1m7.433s 0.1709843554185943 0m56.678s
sin 1.7136493465700289 1m10.654s 1.7136493465700542 0m57.114s
Do you know what causes the lower digits to be different? Is
it that Math and StrictMath use different algorithms, not just
different optimization levels?
