Miller Ulrich Drepper Marek Polacek : Petr Baudis * math/complex.c (csqrtq): NaN and INF fixes. * math/sqrtq.c (sqrt): NaN, INF and < 0 fixes. * math/expm1q.c (expm1q): Changes from GLIBC. Use expq for large parameters. Fix errno for boundary conditions. * math/finiteq.c (finiteq): Add comment. * math/fmaq.c (fmaq): Changes from GLIBC. Fix missing underflows and bad results for some subnormal results. Fix sign of inexact zero return. Fix sign of exact zero return.
