* remove, or replace Xr of ieee to either ilogb, nextafter or scalbnmartynas2009-08-039-29/+27

* now that the pages are split and we track separate HISTORY:martynas2009-07-294-13/+32
| | | | | | | double => 4.3BSD float => NetBSD 1.1 long double => OpenBSD 4.5 scalbln, scalblnf, scalblnl => OpenBSD 4.7
* ieee, and ieeef aren't real, and the amount of functions it documentsmartynas2009-07-295-90/+240
| | | | | is getting ridiculous. split them into groups of copysign, ilogb, nextafter, scalbn. discussed long ago with millert@

* int is big enough to fully represent exponents of all supported fpmartynas2009-07-254-5/+80
| | | | | | | | formats. which even for 80-bit & 128-bit long doubles is only 15 bits. therefore, scalbln, scalblnf, scalblnl are essentially the same as scalbn, scalbnf, scalbnl with bounds checking so that LONG_MIN..INT_MIN, and INT_MAX..LONG_MAX ranges properly raise exceptions & yield correct values. looks good to millert@

* fix scalbn, scalbnf, frexpf on amd64. don't use double argmartynas2009-04-252-10/+16
| | | | | | | | | | float/double prologue/epilogue, since the second argument is not float/double. were never working properly (always returned inf). actually, should help other math funcs (like pow) too, since they use it internally tested by kurt@; devel/boost fp regresses are working better now. ok kurt@
* alias and give frexpf symbol external linkage to scalbnf; this wasmartynas2009-04-212-2/+8
| | | | | | | | overriden by md source. spotted by kurt@ actually; on amd64 scalbnf, scalbn (and therefore now frexpf) have always been broken since second argument is not float. fix is under reviewal / will be committed separately ok kurt@, kettenis@, millert@. tested by kurt@
* make ldexpf behavior consistent with the double and extended-precisionmartynas2009-04-194-72/+10
| | | | | | versions; spotted by kettenis@ while here also remove unused ldexp; it lives in libc ok kettenis@, "looks good" millert@
* in the old days compiler could not convert decimal constantsmartynas2009-04-1114-306/+82
| | | | | | | | | | accurately, hence the tricks in libm, using machine representation of constants. remove kludges and switch to use decimal constants, much simplifying the code. since, the compiler converts them accurately. generated values match on vaxfp discussed with millert@, and miod@ testing todd@, and myself ok millert@

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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@

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - provide proper dtoa locks - use the real strtof implementation - add strtold, __hdtoa, __hldtoa - add %a/%A support - don't lose precision in printf, don't round to double anymore - implement extended-precision versions of libc functions: fpclassify, isnan, isinf, signbit, isnormal, isfinite, now that the ieee.h is fixed - separate vax versions of strtof, and __hdtoa - add complex math support. added functions: cacos, casin, catan, ccos, csin, ctan, cacosh, casinh, catanh, ccosh, csinh, ctanh, cexp, clog, cabs, cpow, csqrt, carg, cimag, conj, cproj, creal, cacosf, casinf, catanf, ccosf, csinf, ctanf, cacoshf, casinhf, catanhf, ccoshf, csinhf, ctanhf, cexpf, clogf, cabsf, cpowf, csqrtf, cargf, cimagf, conjf, cprojf, crealf - add fdim, fmax, fmin - add log2. (adapted implementation e_log.c. could be more acruate & faster, but it's good enough for now) - remove wrappers & cruft in libm, supposed to work-around mistakes in SVID, etc.; use ieee versions. fixes issues in python 2.6 for djm@ - make _digittoint static - proper definitions for i386, and amd64 in ieee.h - sh, powerpc don't really have extended-precision - add missing definitions for mips64 (quad), m{6,8}k (96-bit) float.h for LDBL_* - merge lead to frac for m{6,8}k, for gdtoa to work properly - add FRAC*BITS & EXT_TO_ARRAY32 definitions in ieee.h, for hdtoa&ldtoa to use - add EXT_IMPLICIT_NBIT definition, which indicates implicit normalization bit - add regression tests for libc: fpclassify and printf - arith.h & gd_qnan.h definitions - update ieee.h: hppa doesn't have quad-precision, hppa64 does - add missing prototypes to gdtoaimp - on 64-bit platforms make sure gdtoa doesn't use a long when it really wants an int - etc., what i may have forgotten... - bump libm major, due to removed&changed symbols - no libc bump, since this is riding on djm's libc major crank from a day ago discussed with / requested by / testing theo, sthen@, djm@, jsg@, merdely@, jsing@, tedu@, brad@, jakemsr@, and others. looks good to millert@ parts of the diff ok kettenis@ this commit does not include: - man page changes
