bde 2916ad3e28 Use fabs[f]() instead of bit fiddling for setting absolute values. ... This makes little difference in float precision, but in double precision gives a speedup of about 30% on amd64 (A64 CPU) and i386 (A64). This depends on fabs[f]() being inline and efficient. The bit fiddling (or any use of SET_HIGH_WORD(), which libm does too much because it was best on old 32-bit machines) always causes packing overheads and sometimes causes stalls in the packing, since it operates on only part of a variable in the double precision case. It apparently did cause stalls in a critical path here.		2008-03-30 18:07:12 +00:00
