* The logb() functions are not just ieee754 "test" functions, but areBruce Evans2005-11-061-1/+2
| | | | | | | | | | | | | | | | standard in C99 and POSIX.1-2001+. They are also not deprecated, since apart from being standard they can handle special args slightly better than the ilogb() functions. Move their documentation to ilogb.3. Try to use consistent and improved wording for both sets of functions. All of ieee854, C99 and POSIX have better wording and more details for special args. Add history for the logb() functions and ilogbl(). Fix history for ilogb(). Notes: svn path=/head/; revision=152117

* Many changes, including the following major ones:David Schultz2005-01-231-113/+269
| | | | | | | | | | | | | - Rearrange the list of functions into categories. - Remove the ulps column. It was appropriate for only some of the functions in the list, and correct for even fewer of them. - Add some new paragraphs, and remove some old ones about NaNs that may do more harm than good. - Document precisions other than double-precision.

| | | | | | | | | | | | | - Make some minor rearrangements in the introduction. - Mention the problem with argument reduction on i386. - Add recently-implemented functions to the table. - Un-document the error bounds that only apply to the old 4BSD math library, and fill in the correct values where I know them. No attempt has been made to document bounds lower than 1 ulp, although smaller bounds are usually achievable in round-to-nearest mode. Notes: svn path=/head/; revision=136395

* Memory's free, but all the world ain't a VAX anymore. Bring math.3David Schultz2004-06-191-364/+206
| | | | | | | | | | | | | | | kicking and screaming into the 1980's. This change converts most of the markup from man(7) to mdoc(7) format, and I believe it removes or updates everything that was flat out wrong. However, much work is still needed to sanitize the markup, improve coverage, and reduce overlap with other manpages. Some of the sections would better belong in a philosophy_of_w_kahan.3 manpage, but they are informative and remain at least as reminders of topics to cover.

* J.T. Conklin's latest version of the Sun math library.Jordan K. Hubbard1994-08-191-0/+633
-- Begin comments from J.T. Conklin: The most significant improvement is the addition of "float" versions of the math functions that take float arguments, return floats, and do all operations in floating point. This doesn't help (performance) much on the i386, but they are still nice to have. The float versions were orginally done by Cygnus' Ian Taylor when fdlibm was integrated into the libm we support for embedded systems. I gave Ian a copy of my libm as a starting point since I had already fixed a lot of bugs & problems in Sun's original code. After he was done, I cleaned it up a bit and integrated the changes back into my libm. -- End comments Reviewed by: jkh Submitted by: jtc Notes: svn path=/cvs2svn/branches/msun/; revision=2116
