BTW, the gamma computation shouldn't be at all fragile, unless I've messed
up somewhere: the Lanczos sum is evaluated as a rational function in
which both numerator and denominator have only positive coefficients, so
there's little danger of nasty cancellations boosting the relative error.
I'd be surprised if use of fma instructions made more than 1 or 2 ulps
difference to the result, but I'll take a look. |
