The porting part of this patch fixes bugs on non-IEEE platforms
with frexp, ldexp, logb.
* admin/CPP-DEFINES (HAVE_CBRT, HAVE_LOGB, logb): Remove.
* configure.ac (logb, cbrt): Do not check for these functions,
as they are not being used.
* doc/lispref/numbers.texi (Float Basics, Arithmetic Operations, Math Functions):
Document that / and mod (with floating point arguments), along
with asin, acos, log, log10, expt and sqrt, return special values
instead of signaling exceptions.
(Float Basics): Document that logb operates on the absolute value
of its argument.
(Math Functions): Document that (log ARG BASE) also returns NaN if
BASE is negative. Document that (expt X Y) returns NaN if X is a
finite negative number and Y a finite non-integer.
* etc/NEWS: Document NaNs versus signaling-error change.
* src/data.c, src/lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
Now static.
* src/floatfns.c: Simplify discussion of functions that Emacs doesn't
support, by removing commented-out code and briefly listing the
C89 functions excluded. The commented-out stuff was confusing
maintenance, e.g., we thought we needed cbrt but it was commented out.
(logb): Remove decl; no longer needed.
(isfinite): New macro, if not already supplied.
(isnan): Don't replace any existing macro.
(Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
are present on all C89 platforms.
(Ffrexp): Do not special-case zero, as frexp does the right thing
for that case.
(Flogb): Do not use logb, as it doesn't have the desired meaning
on hosts that use non-base-2 floating point. Instead, stick with
frexp, which is C89 anyway. Do not pass an infinity or a NaN to
frexp, to avoid getting an unspecified result.
* doc/lispref/numbers.texi (Random Numbers): Document new behavior of
the calls (random) and (random STRING).
* etc/NEWS: Document new behavior of (random), (random "string").
* lisp/play/5x5.el, lisp/play/animate.el, lisp/play/cookie1.el:
* lisp/play/dissociate.el, lisp/play/doctor.el, lisp/play/dunnet.el:
* lisp/play/gomoku.el, lisp/play/landmark.el, lisp/play/mpuz.el:
* lisp/play/tetris.el, lisp/play/zone.el:
* lisp/calc/calc-comb.el (math-init-random-base):
* lisp/play/blackbox.el (bb-init-board):
* lisp/play/life.el (life):
* lisp/server.el (server-use-tcp):
* lisp/type-break.el (type-break):
Remove unnecessary call to (random t).
* lisp/net/sasl.el (sasl-unique-id-function):
Change (random t) to (random), now that the latter is more random.
* lisp/play/life.el (life-initialized): Remove no-longer-needed var.
* lisp/gnus/gnus-sync.el (gnus-sync-lesync-setup):
* lisp/gnus/message.el (message-canlock-generate, message-unique-id):
Change (random t) to (random), now that the latter is more random.
* lisp/org/org-id.el (org-id-uuid):
Change (random t) to (random), now that the latter is more random.
* src/emacs.c (main): Call init_random.
* src/fns.c (Frandom): Set the seed from a string argument, if given.
Remove long-obsolete Gentzel cruft.
* src/lisp.h, src/sysdep.c (seed_random): Now takes address and size, not long.
(init_random): New function.
* doc/lispref/intro.texi (A Sample Function Description): Special notation
used for macros too.
* doc/lispref/objects.texi (Ctl-Char Syntax, Other Char Bits): Copyedits.
(Symbol Type): Add xref for keyword symbols.
(Sequence Type): Clarify differences between sequence types.
(Cons Cell Type): Add "linked list" index entry.
(Non-ASCII in Strings): Copyedits.
(Equality Predicates): Symbols with same name need not be eq.
* doc/lispref/numbers.texi (Float Basics): Document isnan, copysign, frexp and
ldexp. Move float-e and float-pi to Math Functions node.
* NEWS: Integer overflow now yields floating-point instead of
wrapping around.
[doc/lispref/ChangeLog]
* numbers.texi (Arithmetic Operations, Math Functions): Large integers go to
floats instead of wrapping around.
* objects.texi (Integer Type): Likewise.
