jtc 6a189fc179 Remove unused static constant "one". 1995-01-25 01:07:23 +00:00
jtc 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
1995-01-25 01:06:35 +00:00
jtc 10a7ebda19 Bug fix from fdlibm 5.2. 1995-01-16 20:05:43 +00:00
cgd 3a370daf86 specify man pages the new way. 1994-12-22 09:44:45 +00:00
jtc 600d3f84d5 Add volatile qualifier to huge and tiny, so that huge*huge and tiny*tiny
are performed at run-time.
1994-12-16 08:38:20 +00:00
jtc c446bbd004 Added s_isinff.c 1994-09-25 17:31:51 +00:00
jtc d797a5d5e9 __infinity[] and isinf() for systems whose C libraries don't supply them;
and isinff(), a "float" version of isinf().
1994-09-25 17:29:47 +00:00
jtc 43e6dd4c8e Add prototype for isinff(). 1994-09-25 17:27:56 +00:00
jtc 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.

jtc b4f978017e Remove CYGNUS_LOCAL comment: I maintain this code for NetBSD, not Cygnus 1994-09-13 00:40:33 +00:00

jtc 9f19de9cde Remove lie (in a comment) about conversion between 80 bit ot 64 bit reals,
since we set up the fpu to do all calculations in 64 bit mode at this time.
1994-08-26 00:20:34 +00:00
jtc 4b2017adfe Assembly language versions of some of the "float" functions. 1994-08-19 03:56:44 +00:00
jtc 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).

jtc 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.

jtc 9a3e07c4c1 Use BYTE_ORDER == LITTLE_ENDIAN instead of -Dnational to select byte order
of floating point numbers.

The assumption that a processor's floats use the same order as its integers
is probably unwarranted, but it is better than requiring non-national CPUs
to #define national, as that drags in national-specific code too.
(According to a comment in the code, the national FPU does not do infinity)
