jtc 977400602b Changed w_gamma.c, w_gamma_r.c, w_gammaf.c, w_gammaf_r.c to call 
__ieee754_lgamma_r or __ieee754_lgammaf_r.
Removed e_gamma.c, e_gamma_r.c, e_gammaf.c, e_gammaf_r.c, e_lgamma.c,
e_lgamma_f.c.

pk 26646c7969 Setup stack-frame correctly (same as s_ilogb.S). 1995-10-22 20:32:43 +00:00
jtc e2143cf975 Fix from Jochen Pohl, i387 version of ilogb didn't set up the stack 
frame correctly (PR #1590).

jtc c1c8f42080 Changed core routines to call __ieee754_sqrt() instead of sqrt(). I 
reported this enhancement to fdlibm-comments, and got the following
reply:

You are right. __ieee754_sqrt should be in use with e_*.c.

jtc ea66efc784 Enable mc68881 versions of remainder() and scalb(). 1995-02-18 01:46:41 +00:00
jtc 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.
 1995-02-18 01:39:51 +00:00
jtc 324e516335 68881-assisted versions of these functions. 1995-02-18 01:24:42 +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

jtc 10a7ebda19 Bug fix from fdlibm 5.2. 1995-01-16 20:05:43 +00:00

jtc 600d3f84d5 Add volatile qualifier to huge and tiny, so that huge*huge and tiny*tiny 
are performed at run-time.

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 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).

minor changes by me.

jtc bdde9305da Use RCSID macro for RCS ID's. 1994-03-18 23:22:10 +00:00
jtc 6d76330bec Added RCS ID's. ID's use new RCSID macro from <machine/asm.h>. 1994-03-12 01:30:22 +00:00
jtc d72111c735 Update for mc68881 ceil(), floor(), & rint(), and s_sqrt.S -> e_sqrt.S

jtc 41dbc84e05 The hardware sqrt function is supposed to be __ieee754_sqrt(), and live in 
e_sqrt.S.

jtc c9566fe572 Replace code that was "truncated" when it was converted from old 
math library.
 1994-03-12 01:09:29 +00:00
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.
