* | math: fix i386/expl.s with more precise x*log2e | Szabolcs Nagy | 2012-12-14 | 1 | -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 | ||||
