Bruce Evans 487ddb8fa4 Compute (1 - x^2) as ((1 - x) * (1 + x)) instead of as (1 - x * x) to ... avoid easily avoidable loss of precision when |x| is nearly 1. Extended (64-bit) precision only moves the meaning of "nearly" here. This probably could be done better by splitting up the range into |x| <= 0.5 and |x| > 0.5 like the C version. However, ucbtest does't report any errors in this version. Perhaps the C version should be used anyway. It's only 25% slower now on a P5, provided the C version of sqrt() isn't used, and the C version could be optimized better. Errors checked by: ucbtest		1997-02-20 12:37:49 +00:00
