* Reduce libm's exports and make internal calls go direct.guenther2016-09-12293-563/+1511
| | | | | | All dependencies on libc are now via reserved/standardized names. ok kettenis@ millert@ deraadt@
* Per fpclassify(3): isinff(), isnanf(), finite(), and finitef() are deprecatedguenther2016-09-1225-81/+81
| | | | | | in favor of isinf(), isnan(), and isfinite(). ok tb@ martynas@
* Use fe*() routines from <fenv.h> instead of fp*() routines from <ieeefp.h>guenther2016-09-121-10/+11

* Use \(mi instead of - for the mathematical minus sign as recommended bytb2016-06-011-7/+7
| | | | | | | mandoc_char(7). While there, use some spacing around the arithmetic operations to make the more complicated formulas a bit easier to read. looks good to kettenis, no objection from schwarze

* remove hppa64 port, which we never got going beyond broken single users.deraadt2016-05-111-3/+1
| | | | | | hppa reverse-stack gives us a valuable test case, but most developers don't have a 2nd one to proceed further with this. ok kettenis

* Remove predefined strings from libm pages.tb2016-04-2621-128/+103
| | | | With lots of help, input and tweaks and finally ok schwarze@
* for some time now mandoc has not required MLINKS to functionjmc2016-03-301-202/+1
| | | | | | | | | | | | correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added. MLINKS will still work, and remain for perl to ease upgrades; ok nicm (curses) bcook (ssl) ok schwarze, who provided a lot of feedback and assistance ok tb natano jung

| | | | lots of agreement.
* Fix wrong answer if the imaginary part is zero.shadchin2015-12-183-3/+9
| | | | | | NetBSD also turn off this piece of code. ok tb@
* Fix behavior csqrt, should beshadchin2015-12-183-6/+6
| | | | | | | | | | | csqrt(conj(z)) == conj(csqrt(z)) Before csqrt(-4.0 + -0.0i) = 0.0 + 2.0j but should be csqrt(-4.0 + -0.0i) = 0.0 - 2.0j ok tb@, also discussed with daniel@
* update NAME section to include all documented functions,jmc2015-11-102-6/+10

* From FreeBSD 23397:shadchin2015-11-061-7/+7
| | | | | | | | | | | | | Fixed wrong magic numbers in scaling. hypotf() was very broken for large and small values: hypotf(2.3819765e+38, 2.0416943e+38) was NaN instead of 3.1372484e+38 hypotf(-3.4028235e+38, 3.3886450e+38) was NaN instead of Inf hypotf(-2.8025969e-45, -2.8025969e-45) was 0 instead of 4.2038954e-45 Found by: ucbtest ok miod@

* Signs of cacosh/cacoshf were not always correct (e.g., -1.1 -1.1i),martynas2015-07-162-4/+4
| | | | | | as found by fortran regression tests. Also added some complex regression tests for cacosh, casinh, catanh. Reported by John Marino @ DragonFlyBSD.

* Provide a sparc64 version of sqrtl(3) that simply calls _Qp_sqrt.kettenis2014-09-122-1/+31
| | | | | The generic sqrtl(3) is not nearly accurate enough for quad-precision floating point.

| | | | | | | | | | | | | | | | | | | | members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@
