* use sys/cdefs.h; pointed out by theomartynas2008-12-101-2/+2

* - 80-bit and quad precision trigonometric and other mostmartynas2008-12-091-14/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | important functions: acosl, asinl, atanl, atan2l, cosl, sinl, tanl, exp2l, frexpl, ilogbl, ldexpl, logbl, scalbnl, fabsl, hypotl, powl, sqrtl, rintl, copysignl, nanl, fdiml, fmaxl, fminl. mostly taken from freebsd, needed alot of changes to adapt. note, these are all c versions; and are quite slow when architectures have, e.g. sqrt. assembly versions will be added afterwards - make them .weak/__weak_alias to the double precision versions on other archs - no need to have two finites. finite() and finitef() are non-standard 3BSD obsolete versions of isfinite. remove from libm. make them weak_alias in libc to __isfinite and __isfinitef instead. similarly make 3BSD obsolete versions of isinf, isinff, isnan, isnanf weak_aliases to C99's __isinf, __isinff, __isnan, __isnanf - remove unused infinity.c. the c library has infinities for each supported platform - use STRICT_ASSIGN cast hack for _kernel_rem_pio2, so that the double version has a chance of working on i386 with extra precision - avoid storing multiple copies of the pi/2 array, since it won't vary - bump major due to removed finite/finitef. although they will be in libc, which anything is linked to, minor bump might be enough ok millert@. tested by sthen@, jsg@, ajacoutot@, kili@, naddy@
* - remove isinff, isnanf. this has been moved to libcmartynas2008-07-241-25/+1
| | | | | | | | | | | - remove never-enabled signbit. libc has is now - add C99 implementations, from freebsd, for nan(), nanf() (needed to write _digittoint for it), exp2(), exp2f(), remquo(), remquof(), needed STRICT_ASSIGN macro for math_private.h - bump major man pages will follow exp2{,f} has been requested by chl@ ok millert@
* fix cases, found by lint:martynas2008-07-181-2/+4
| | | | | | | | - actually raise inexacts for expm1, and support - __exp__E always returns, because inexact check always succeeds. add NOTREACHED - some cases in lgamma FALLTHROUGH, as intended ok millert@
* properly raise inexact; ok millert@martynas2008-07-171-2/+2

* some archaic 'n = a(b), c(d)' use that confused lintmartynas2008-07-161-3/+11
| | | | ok millert@
* - expressions such as x != x and x == x are prone to errors andmartynas2008-06-251-6/+7
| | | | | | | | | ugly, when we have isnan and isinf - no need to check for _IEEE, when checking for not-a-number - remove some impossible checks - while here, drem->remainder, as drem is just an obsolete alias now ok millert@
* cleaning up, no functional changesmartynas2008-06-211-71/+35
| | | | | | | - no support for National 32000, removing ns32000/national ifdefs maze - remove tahoe defs - ansify looks fine to millert@; who also noticed rint removal
* fix some errors found by lint, e.g. declaration w/o types, makemartynas2008-06-161-5/+5
| | | | | zero const. also do the same fix as was found for ieee's trunc by lint; ok millert@. tested on VAX
* spacing, add rcs ids, no binary changemartynas2008-06-121-1/+2
|
* some cleanup for noieee_src, as asked by millert@: remove fictionalmartynas2008-06-121-0/+1
| | | | | includes, include math.h where needed and remove redundant declarations ok millert@
* drem{,f} are aliases for remainder{,f}, so:martynas2008-06-111-79/+86
| | | | | | | | | | - document and mlink drem{,f} - drem->remainder on noieee, and make drem an alias - finite returns integer, n_support.c - general n_support.c ansification and cleanup - drem is now an ALTENTRY for remainder, in n_support.S help with man page from jmc@ and millert@ ok millert@
* add __signbit/__signbitf/__signbitl; nothing uses this file, it's justjason2007-05-311-0/+24
| | | | for completeness.
* Remove the advertising clause in the UCB license which Berkeleymillert2003-06-021-5/+1
| | | | rescinded 22 July 1999. Proofed by myself and Theo.
* scalb() in vax libm is in fact scalbn(), so change the symbol name.miod2002-10-111-8/+8
| | | | | | Only affects vax, which has no shared libraries, so no version change needed for libm. Someone with enough math skills ought to code a real scalb() on a rainy day...
