8961dd234b Special case 0, as was done in s_scalbn.S. 
I'm only doing this for consistancy --- someone really needs to measure
whether this optimization is justified.

3d9c0cdc87 Integrate last of the relavant changes from fdlibm 5.2: 
4. Performance issue on rem_pio2
       An attempt to speed up the argument reduction in the trig function is to
       consider pi/4 < x < 3pi/4 a special case. This was done in the file
       e_rem_pio2.c

d1f06e0b8f LIBM_SCCS must be defined for the RCS ID to be defined. 
This library will soon be used by DJGPP.  And since memory is often tight
on DOS machines, there is little benifit to be had from including RCS IDs.

4b2017adfe Assembly language versions of some of the "float" functions. 1994-08-19 03:56:44 +00:00

1af6796a8d The fyl2xp1 instruction has a limited range: 
-(1 - (sqrt(2) / 2)) <= x <= sqrt(2) - 1
so we can't use it.

Also, I'm not sure fyl2xp1's extra precision will
matter once the result is converted from extended
real (80 bits) back to double real (64 bits).

593d18fc49 Added a ieee_test(3) man page (Like SunOS) derrived from an earlier copy 
of ieee(3).  This man page describes logb, scalb, and significand, which
are really only useful for verifying IEEE754 compliance.
