62f7d2f10d More updates for math(3):
- 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.

7aef999db6 Fix two bugs in the signbit() macro, which was implemented last year:
- It was added to libc instead of libm.  Hopefully no programs rely
  on this mistake.

- It didn't work properly on large long doubles because its argument
  was converted to type double, resulting in undefined behavior.

370370ec79 Add C99's nearbyint{,f}() functions as wrappers around rint().
These trivial implementations are about 25 times slower than
rint{,f}() on x86 due to the FP environment save/restore.
They should eventually be redone in terms of fegetround() and
bit fiddling.

dd81b94d1c Add trivial implementations of scalbln() and scalblnf().
These routines are specified in C99 for the sake of
architectures where an int isn't big enough to represent
the full range of floating-point exponents.  However,
even the 128-bit long double format has an exponent smaller
than 15 bits, so for all practical purposes, scalbln() and
scalblnf() are aliases for scalbn() and scalbnf(), respectively.

5cfbdc1d4a Memory's free, but all the world ain't a VAX anymore. Bring math.3
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.

2a8fd4fc31 J.T. Conklin's latest version of the Sun math library.
-- 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
