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).	26 years ago
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!	26 years ago
Guido van Rossum	8586991099	REMOVED all CWI, CNRI and BeOpen copyright markings. This should match the situation in the 1.6b1 tree.	26 years ago
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	26 years ago
Peter Schneider-Kamp	10e1bf2f64	remove all occurence of math.rint() from the sources (and yes, "Currintly" also counts <0.5 wink>)	26 years ago
Peter Schneider-Kamp	7e01890986	merge Include/my.h into Include/pyport.h marked my.h as obsolete	26 years ago
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 ;)	26 years ago
Tim Peters	489d54ef66	Typo repair in docstring -- my fault.	26 years ago
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".	26 years ago
Tim Peters	c9c02c4cf3	Repair docs for math.frexp (they were wrong). Reported on c.l.py by Kirill Simonov.	26 years ago
Guido van Rossum	ffcc3813d8	Change copyright notice - 2nd try.	26 years ago
Guido van Rossum	fd71b9e9d4	Change copyright notice.	26 years ago
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.	26 years ago
Guido van Rossum	71260b846e	Added math.rint() -- round according to current IEEE754 mode	26 years ago
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.]	26 years ago

Roger E. Masse	20c6381856	Removed references to getdoublearg and get2doublearg rename macros and substituted the appropriate PyArg_Parse calls. Retested. All appears well.	30 years ago
Guido van Rossum	4a4880966b	Correct another mistake (initmath() always fell through to fatal error). Watch it, Barry! :-)	30 years ago
