Fix style, documentation for rounding functions and multiple values.
src/ChangeLog addition:
2010-08-30 Aidan Kehoe <kehoea@parhasard.net>
* floatfns.c (ceiling_one_mundane_arg, floor_one_mundane_arg)
(round_one_mundane_arg, truncate_one_mundane_arg):
INTEGERP is always available, no need to wrap calls to it with
#ifdef HAVE_BIGNUM.
(Fceiling, Ffloor, Fround, Ftruncate, Ffceiling, Fffloor)
(Ffround, Fftruncate):
Correct some code formatting here.
* doprnt.c (emacs_doprnt_1):
Remove some needless #ifdef WITH_NUMBER_TYPES, now number.h is
always #included.
man/ChangeLog addition:
2010-08-30 Aidan Kehoe <kehoea@parhasard.net>
* lispref/eval.texi (Evaluation, Multiple values):
Document our implementation of multiple values; point the reader
to the CLTL or the Hyperspec for details of exactly when values
are discarded.
* lispref/numbers.texi (Numeric Conversions): Document the
optional DIVISOR arguments to the rounding functions, and
document that they all return multiple values.
(Rounding Operations): Ditto.
* cl.texi (Multiple Values):
Document that we've moved the multiple values implementation to
core code, and cross-reference to the Lispref.
(Numerical Functions): The various rounding functions are now
identical to the built-in rounding functions, with the exception
that they return lists, not multiple values; document this.
