https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235413 Bug ID: 235413 Summary: [LIBM] optizimation for cexp and cexpf Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: kargl@FreeBSD.org Created attachment 201620 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=201620&action=edit patch The attach patch utilizes sincos[f] in the computation of cexp[f]. For 20 million random z=x+Iy drawn in the box defined by x,y in [0,MAX_EXP*LN2], this amounts to a 8.7% and 11.4% speed improvement over computing sin[f] and cos[f] individually in cexp[f]. -- You are receiving this mail because: You are the assignee for the bug.home | help
