CVS commit: src/lib/libc/stdlib

[Matthias Drochner <drochner%netbsd.org@localhost>]

Module Name:    src
Committed By:   drochner
Date:           Wed Mar 22 21:06:03 UTC 2006

Added Files:
        src/lib/libc/stdlib: erand48_ieee754.c

Log Message:
Rewrite erand48() to put the random bits into the mantissa by simple
bitshifts instead of calling ldexp() three times.
(for ieee doubles only -- vax can't use it, so the old version
needs to stay around)
This removes the dependency on ldexp() which also didn't participate in
the usual __RENAME game, thus lead to confusion.
In addition, this version is almost 3 times as fast for me.
