Now numbers from BigNumber trig calls use the default constructor rather than create a new one each time. Now all trig functions can have arguments with higher precisions.

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.
