Tim Peters 1d120619d4 Stop raising OverflowError on underflows reported by libm (errno==ERANGE and 
libm result is 0).  Cautiously add a few libm exception test cases:
1. That exp(-huge) returns 0 without exception.
2. That exp(+huge) triggers OverflowError.
3. That sqrt(-1) raises ValueError specifically (apparently under glibc linked
   with -lieee, it was raising OverflowError due to an accident of the way
   mathmodule.c's CHECK() macro happened to deal with Infs and NaNs under gcc).

Tim Peters 78fc0b57df Fixed legit gripe from c.l.py that math.fmod docs aren't confusing enough. 
FRED, please check my monkey-see-monkey-do Tex fiddling!

Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings. 
This should match the situation in the 1.6b1 tree.

Barry Warsaw 9bfd2bf5ed Do the absolute minimal amount of modifications to eradicate 
Py_FatalError() from module initialization functions.  The importing
mechanism already checks for PyErr_Occurred() after module importation
and it Does The Right Thing.

Unfortunately, the following either were not compiled or tested by the
regression suite, due to issues with my development platform:

	almodule.c
	cdmodule.c
	mpzmodule.c
	puremodule.c
	timingmodule.c

Peter Schneider-Kamp 10e1bf2f64 remove all occurence of math.rint() from the sources 
(and yes, "Currintly" also counts <0.5 wink>)
 2000-08-10 04:23:30 +00:00
Peter Schneider-Kamp 7e01890986 merge Include/my*.h into Include/pyport.h 
marked my*.h as obsolete

Thomas Wouters f3f33dcf03 Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)', 
and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.

All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:

long
func(a, b)
	long a;
	long b; /* flagword */
{

and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)

Tim Peters 489d54ef66 Typo repair in docstring -- my fault. 2000-07-03 22:41:34 +00:00
Fred Drake 40c48685a2 ANSI-fication, remove Py_PROTO, etc. 
Revise math_1(), math_2(), stub-generating macros, and function tables to
use PyArg_ParseTuple() and properly provide the function name for error
message generation.
Fix pow() docstring for MPW 3.1; had said "power" instead of "pow".
 2000-07-03 18:11:56 +00:00
Tim Peters c9c02c4cf3 Repair docs for math.frexp (they were wrong). 
Reported on c.l.py by Kirill Simonov.

Guido van Rossum c9a5f343bc The addition of rint() (by Peter Schneider-Kamp; I forgot to mention 
that before) in the previous patch has one problem; rint() is not in
the C math library on all platforms (e.g. not for VC++).  Make it
conditional on HAVE_RINT.
 2000-05-11 18:42:27 +00:00
Guido van Rossum 71260b846e Added math.rint() -- round according to current IEEE754 mode 2000-05-11 18:19:42 +00:00
Guido van Rossum c554505ca1 Trent Mick: 
Fix overflow bug in ldexp(x, exp). The 'exp' argument maps to a C int for the
math library call [double ldexp(double, int)], however the 'd'
PyArg_ParseTuple formatter was used to yield a double, which was subsequently
cast to an int. This could overflow.

[GvR: mysteriously, on Solaris 2.7, ldexp(1, 2147483647) returns Inf
while ldexp(1, 2147483646) raises OverflowError; this seems a bug in
the math library (it also takes a real long time to compute the
Inf outcome).  Does this point to a bug in the CHECK() macro?  It
should have discovered that the result was outside the HUGE_VAL range.]

Roger E. Masse 20c6381856 Removed references to getdoublearg and get2doublearg rename macros and

 1996-12-18 21:59:01 +00:00
Guido van Rossum 4a4880966b Correct *another* mistake (initmath() always fell through to fatal error). 
Watch it, Barry! :-)
