2013-08-15math: fix x86 expl.s to raise underflow and clean up special case handlingSzabolcs Nagy-23/+16
2012-12-16math: x86_64 version of expl, fixed some comments in the i386 versionSzabolcs Nagy-2/+2
2012-12-14math: fix i386/expl.s with more precise x*log2eSzabolcs Nagy-1/+107
with naive exp2l(x*log2e) the last 12bits of the result was incorrect for x with large absolute value with hi + lo = x*log2e is caluclated to 128 bits precision and then expl(x) = exp2l(hi) + exp2l(hi) * f2xm1(lo) this gives <1.5ulp measured error everywhere in nearest rounding mode
