Tim Peters daec961e09 Changed Karatsuba cutoff to match current reality. 2004-08-30 23:18:23 +00:00
Guido van Rossum 7aa56c9a7f test_float_overflow(): make shuge (added last week) a little less
huge.  On older Linux systems, the C library's strtod() apparently
gives up before seeing the end of the string when it sees so many
digits that it thinks the result must be Infinity.  (It is wrong, BTW
-- there could be an "e-10000" hiding behind 10,000 digits.)  The
shorter shuge still tests what it's testing, without relying on
strtod() doing a super job.

Neal Norwitz abcb0c03ad Fix SF bug# 676155, RuntimeWarning with tp_compare
Check return value of PyLong_AsDouble(), it can return an error.

Walter Dörwald f171540ab8 Change int() so that passing a string, unicode, float or long argument
that is outside the integer range no longer raises OverflowError, but
returns a long object instead.

This fixes SF bug http://www.python.org/sf/635115

Tim Peters 7f270ba860 Added a test specifically to tickle Karatsuba; it costs no appreciable
runtime.

Tim Peters d0876b859d test_division(): Added one larger digits value, to ensure that the
"lopsided Karatsuba" driver also gets some exercise.

Tim Peters 28b0e2a7f8 Machines-- and Python --are a lot faster in relevant ways since this
test was written.  So boosted the number of "digits" this generates, and
also beefed up the "* / divmod" test to tickle numbers big enough to
trigger the Karatsuba algorithm.  It takes about 2 seconds now on my box.

Barry Warsaw 04f357cffe Get rid of relative imports in all unittests. Now anything that
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".

This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).

Now Tim and Jack can have at it. :)

Neal Norwitz 05c09d08f9 Format strings (tuples,) appropriately 2002-04-01 19:01:39 +00:00
Tim Peters 785261684e Return reasonable results for math.log(long) and math.log10(long) (we were
getting Infs, NaNs, or nonsense in 2.1 and before; in yesterday's CVS we
were getting OverflowError; but these functions always make good sense
for positive arguments, no matter how large).

Tim Peters 0dad0f763c Revert one of the "division fixes" in test_long. It intends to try both
"/" and "//", and doesn't really care what they *mean*, just that both
are tried (and that, whatever they mean, they act similarly for int and
long arguments).
2001-09-04 19:48:01 +00:00
Guido van Rossum 54e54c6877 The first batch of changes recommended by the fixdiv tool. These are
mostly changes of / operators into //.  Once or twice I did more or
less than recommended.

Tim Peters 83e7ccc9fd Whitespace normalization. 2001-09-04 06:37:28 +00:00
Tim Peters 9fffa3eea3 Raise OverflowError when appropriate on long->float conversion. Most of
the fiddling is simply due to that no caller of PyLong_AsDouble ever
checked for failure (so that's fixing old bugs).  PyLong_AsDouble is much
faster for big inputs now too, but that's more of a happy consequence
than a design goal.

Tim Peters 32f453eaa4 New restriction on pow(x, y, z): If z is not None, x and y must be of
integer types, and y must be >= 0.  See discussion at

Tim Peters a365309528 Add a test for the new // operator too. 2001-08-23 23:02:57 +00:00
Tim Peters 26c7fa355a SF bug [#454456] int overflow code needs tests.
Added tests for boundary cases in magical PEP 237 int->long auto-overflow,
but nothing here addresses the rest of the bug report so left it open.

Tim Peters 971e0690c4 Remove test_long's expected-output file. 2001-08-23 20:34:01 +00:00
Marc-André Lemburg 3661908a6a This patch removes all uses of "assert" in the regression test suite
and replaces them with a new API verify(). As a result the regression
suite will also perform its tests in optimization mode.

Fred Drake 004d5e6880 Make reindent.py happy (convert everything to 4-space indents!). 2000-10-23 17:22:08 +00:00
Guido van Rossum 6e277cf7de Christian Tismer: added test to ensure that multiplication commutes.
[The test is in a slightly odd place, in test_division_2; but it
exercises the recent change to long_mult(), and that's all we really
ask for.  --GvR]

Fred Drake db1bd5c230 Revise tests to support str(<long int object>) not appending "L". 1999-12-23 15:36:42 +00:00
