 Since +pi+ is not the mathematical pi, (sin +pi+) cannot be zero.

 This is caused by doing a sloppy pi reduction for small args.

 I think this is fixed.  Spot checks show that the results are accurate.

     Fix ticket:5

     o Implement better pi reduction and also always do pi reduction.
     o Add test for sin(pi) and cos(2^120), to test pi reduction.
     o Accuracy for erfc is only 198 bits.
