Cleaned up test cases by removing string comparisons on NaN and 0 equality for bignumbers. Also, now ensuring that sin returns with correct precision.

Failed at adding gamma to the parser (attempted to add 1 to all the values while using gamma, then tried to wierdly overload ! token). I added BigNumber integer support for gamma to allow more flexibility when integrating it into the parser (if that is something that is done).

Fix the test case so it passes on all hardware.
...
The fix is to test that the imaginary part is nonzero,
not that it is exactly 1e-100.
In some software / hardware combos,
it seems to return 1.0000000000000001e-100.
