aymeric 839708d0cf revert previous (obviously wrong) change 2001-05-26 16:49:58 +00:00
aymeric 4d029c3f35 Make this compile when _USE_WRITE is defined 2001-05-22 08:31:27 +00:00
bjh21 fe6fa58436 Add support for ARM VFP-format doubles, conditional on __VFP_FP__. 2001-02-21 18:09:25 +00:00
bjh21 b2ffea9b75 __arm26__ || __arm32__ -> __arm__ 
Not least because the unified NetBSD/arm compiler probably won't predefine
__arm26__ or __arm32__.

christos fe98f4b896 remove redundant declarations; use __MATH_PRIVATE__ to override math.h 
declarations.

bjh21 6c97e2bd78 Initial commit of arm26 port 2000-05-09 21:55:44 +00:00
kleink 9ef6f05359 G/C this copy of <math.h> in favor of the version found in basesrc/include, 
which is actually the one installed.  The latter (which is derived from this
file) has evolved since, and the argument that it is exlusively associated
with libm (and thus should be installed from this directory) no longer holds
since two interfaces (isinf() and isnan()) are part of libc these days.

mark ce67b636ad Get the word order of doubles correct for the arm32 port. 
Note: The arm32 port is little endian except for the FP word order.

phil d9f99fc936 Removing a "volatile" put there for the ns32k which is no longer needed. 1996-04-08 15:43:41 +00:00
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.

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

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

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

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 39abd30929 Don't determine byte order at run time. 
This also "solves" the problem of GCC optimization leading to incorrect
results.
