sin(x) & cos(x) for x = 10²² in radians

[dm319]

I keep finding more!

Galculator:

sin 1e22 : -0.852200849767
cos 1e22 : 0.5232147854

Quite impressed with this, it must mean that galculator implements a different maths library to R/python etc., I guess in BCD because it can do 0.3 - 0.2 without trouble. Probably Intel BCD I'm guessing, or else much higher precision floating point binary.

Android Calculator:

cos(1^22) : 0.5403023058681397174009...

sin(1^22) : 0.8414709848078078965066...

I wonder where it's going wrong for some of these... the numbers aren't far out, but the sign is often wrong.
