sin_pi(x) is only called for x < 0 and |x| < 2**(p-1) where p is the precision of x. The new argument reduction is an optimization compared to the old code, and it removes a chunk of dead code. Accuracy tests in the intervals (-21,-20), (-20,-19), ... (-1,0) show no differences between the old and new code. Obtained from: bde |
