joerg 839c0958b5 PR 36988: ISO C99 mandates that HUGE_VAL, HUGE_VALF, HUGE_VALL and
INFINITY are constant expressions.

Use the GCC builtins if possible to implement them.

martin c79c3eed1d Make NAN a compile time constant (with help from the compiler). Suggested
by krister. Fixes PR 40695.
Make references to the old construct (which we can't remove for binary
compatibility reasons) emit a linker warning.

drochner 7161d089aa -get cabs() and cabsf() out of public view - these are historical and
conflict with C99 functions which are builtins in newer gcc
 (actually, the old cabs() is ABI compatible with the new _complex one
  on i386, but this is purely accidental)
 remove public prototypes and manpages, move the code into a compat
 subdirectory as libc does so that binary compatibility is kept
-add a manpage for the isgreater() etc macros, borrowed from FreeBSD
2007-02-22 22:08:17 +00:00
drochner a981c4eb78 add the isgreater() at al. comparision macros defined in C99 and SUSv3;
use just the primitive macros for now (identical to FreeBSD/DragonFly)
which don't use gcc internals, the rest can go in after some testing;

matt, kleink, others. Approved by christos.

junyoung bc836a3102 lib/24252: Add C99 functions round(3) and roundf(3).
libm minor unchanged; ride a recent bump.

From FreeBSD.

drochner 147d852dbc being here, add the (l)lround(f) functions to libm
(almost the same like lrint)
2004-07-01 16:09:21 +00:00

drochner 737ab05bf9 Add (l)lrint(f).
Being here, move some C99 function declarations into the appropriate
section (as discussed with kleink).

kleink 8e54f10bf7 * Turn isinf(3) and isnan(3) into C99-style macros.
* Make it possible for ports to override these (i.e., VAX).
* Remove isnanl(), which was internal to libc only.

kleink 642c4f3f10 Make lint happy for __fpmacro_unary_floating() users. 2004-03-04 00:17:44 +00:00
kleink 15afe0b4fc Move FP_ROP and FP_DIRTYZERO from <math.h> to <vax/math.h> (where they
would have ended up if I hadn't missed the latter file in the commit).
2004-01-20 19:52:40 +00:00

kleink d82e732345 Add C99 fpclassify(), isfinite(), isnormal(), and signbit() macros. 2004-01-15 19:43:44 +00:00
kleink 793c50136c C99 7.12#4: provide INFINITY, which defaults to HUGE_VALF.
If infinities are not available, the machine-dependent header must define
__INFINITY as a positive constant of type float that overflows.

kleink adb0aada40 C99: provide HUGE_VALF and HUGE_VALL. 2003-10-25 22:35:46 +00:00
thorpej 200111747f Add long double support. 2003-05-17 20:42:28 +00:00
bjh21 4be7a2dcf3 Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
  can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
  various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
  !defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them.  In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

simonb 2d8577fb83 Clean up some rampant code duplication wrt ieee number handling:
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).

a single-precision quiet NaN; only to be defined on platforms that do support
this value.
