            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

patch

The attach patch utilizes sincos[f] in the computation
of cexp[f].  For 20 million random z=3Dx+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].
