Mark Dickinson 22999a69e1 Issue #5829: complex('1e-500') shouldn't raise an exception.
Also fix some confusing indentation.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread:
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

Alexandre Vassalotti 80af6da748 Fixed complex.__getnewargs__() to not emit another complex object. 2008-06-04 20:41:44 +00:00

Christian Heimes 6f34109384 I finally got the time to update and merge Mark's and my trunk-math branch. The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math.
The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)

Christian Heimes 2f0da53d28 Fixed repr() and str() of complex numbers. Complex suffered from the same problem as floats but I forgot to test and fix them. 2008-02-15 06:57:08 +00:00

Jeffrey Yasskin 2f3c16be73 Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (just
the complex_pow part), r56649, r56652, r56715, r57296, r57302, r57359, r57361,
r57372, r57738, r57739, r58017, r58039, r58040, and r59390, and new
documentation. The only significant difference is that round(x) returns a float
to preserve backward-compatibility. See http://bugs.python.org/issue1689.

Guido van Rossum 715ec1818d Patch # 1507 by Mark Dickinson. Make complex(x, -0) retain the sign of
the imaginary part (as long as it's not complex).
Backport candidate?

Martin v. Löwis 6819210b9e PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.

Georg Brandl 2b869943fa Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
to complex using its __complex__() method before falling back to the
__float__() method. Therefore, the functions in the cmath module now
can operate on objects that define a __complex__() method.

Collin Winter e38051db87 Patch #1491866: change the complex() constructor to allow parthensized forms. This means complex(repr(x)) now works instead of raising a ValueError. 2007-03-09 20:33:07 +00:00
Neal Norwitz 0593de32d9 Fix SF #1676971, Complex OverflowError has a typo 2007-03-09 05:59:01 +00:00
Neal Norwitz 4b0a315c31 Use sizeof(buffer) instead of duplicating the constants to ensure they won't
be wrong.

The real change is to pass (bufsz - 1) to PyOS_ascii_formatd and 1
to strncat.  strncat copies n+1 bytes from src (not dest).

Reported by Klocwork #58.

Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Tim Peters 465fa3dac4 complex_new(): This could leak when the argument was neither string nor
number.  This accounts for the 2 refcount leaks per test_complex run
Michael Hudson discovered (I figured only I would have the stomach to
look for leaks in floating-point code <wink>).

Walter Dörwald 5ecd6c4db2 Fix typo in comment. 2003-06-17 20:22:24 +00:00
Guido van Rossum 4eadfa2b2e Fix from Greg Chapman from SF bug #695651: a complex subclass
constructor, when passed a single complex argument, returns the
argument unchanged.  This should be done only for the complex base
class; a complex subclass should of course cast the value to the
subclass in this case.

The fix also revealed a segfault in complex_getnewargs(): the argument
for the Py_BuildValue() format code "D" is the *address* of a
Py_complex struct, not the value.  (This corroborated by the API
documentation.)

I expect this needs to be backported to 2.2.3.
2003-03-02 13:51:47 +00:00
Guido van Rossum 5d9113d8be Implement appropriate __getnewargs__ for all immutable subclassable builtin
types.  The special handling for these can now be removed from save_newobj().
Add some testing for this.

Also add support for setting the 'fast' flag on the Python Pickler class,
which suppresses use of the memo.

Raymond Hettinger 604cd6ae79 complex() was the only numeric constructor that created a new instance
when given its own type as an argument.
2002-08-29 14:22:51 +00:00
Guido van Rossum e3a8e7ed1d Call me anal, but there was a particular phrase that was speading to
comments everywhere that bugged me: /* Foo is inlined */ instead of
/* Inline Foo */.  Somehow the "is inlined" phrase always confused me
for half a second (thinking, "No it isn't" until I added the missing
"here").  The new phrase is hopefully unambiguous.

Added related unittests.

Guido van Rossum 69cf3c7641 Deprecate % as well. The message for deprecation of //, % and divmod
is the same in all three cases (mostly because // calls divmod :-).
2002-04-15 12:39:12 +00:00
Guido van Rossum 9ec4c78a54 SF bug #543387.
Complex numbers implement divmod() and //, neither of which makes one
lick of sense.  Unfortunately this is documented, so I'm adding a
deprecation warning now, so we can delete this silliness, oh, around
2005 or so.

Bugfix candidate (At least for 2.2.2, I think.)

Tim Peters 077f27141f SF bug 543840: complex(string) accepts strings with \0

Tim Peters bab22beda8 SF bug 533198: Complex power underflow raises exception.
Konrad was too kind.  Not only did it raise an exception, the specific
exception it raised made no sense.  These are old bugs in complex_pow()
and friends:

1. Raising 0 to a negative power isn't a range error, it's a domain
   error, so changed c_pow() to set errno to EDOM in that case instead
   of ERANGE.

2. Changed complex_pow() to:

A. Used the Py_ADJUST_ERANGE2 macro to try to clear errno of a spurious
   ERANGE error due to underflow in the libm pow() called by c_pow().

B. Produced different exceptions depending on the errno value:
   i) For errno==EDOM, raise ZeroDivisionError instead of ValueError.
      This is for consistency with the non-complex cases 0.0**-2 and
      0**-2 and 0L**-2.
   ii) For errno==ERANGE, raise OverflowError.

Bugfix candidate.

Fred Drake 526c7a0101 Ensure that complex() only accepts a string argument as the first arg,
and only if there is no second arg.

Barry Warsaw 01d697a067 complex_to_buf(), complex_subtype_from_c_complex(): Conversion of
sprintf() to PyOS_snprintf() for buffer overrun avoidance.

complex_print(), complex_repr(), complex_str(): Call complex_to_buf()
passing in sizeof(buf).
2001-11-28 20:50:56 +00:00
Guido van Rossum 70e3688364 complex_subtype_from_string(): move the declaration of s_buffer[] out
of the if block where it was before.  The name is only used inside
that if block, but the storage is referenced outside it via the 's'
variable.

(This patch was part of SF patch #474590 -- RISC OS support.)
