* New restriction on pow(x, y, z): If z is not None, x and y must be ofTim Peters2001-09-031-9/+9
| | | | | integer types, and y must be >= 0. See discussion at http://sf.net/tracker/index.php?func=detail&aid=457066&group_id=5470&atid=105470
* Revert the previous patch to test_pow.py and move the test to test_unary.pyFred Drake2001-08-301-10/+0
| | | | | based on a suggestion from Tim Peters; also make sure that we're really doing exponentiation and not multiplication.
* Added a regression test for the negation-of-exponentiation optimizationFred Drake2001-08-301-0/+11
| | | | bug from compile.c. (SF bug #456756.)
* Make the test pass now that 10**-15 returns a float instead of raisingGuido van Rossum2001-07-121-3/+1

* Update the code to better reflect recommended style:Fred Drake2000-12-121-2/+2
| | | | | Use != instead of <> since <> is documented as "obsolescent". Use "is" and "is not" when comparing with None or type objects.
* Make reindent.py happy (convert everything to 4-space indents!).Fred Drake2000-10-231-24/+24

* SF bug 115831 and Ping's SF patch 101751, 0.0**-2.0 returns inf rather thanTim Peters2000-10-061-30/+55
| | | | | | | | | | raise ValueError. Checked in the patch as far as it went, but also changed all of ints, longs and floats to raise ZeroDivisionError instead when raising 0 to a negative number. This is what 754-inspired stds require, as the "true result" is an infinity obtained from finite operands, i.e. it's a singularity. Also changed float pow to not be so timid about using its square-and-multiply algorithm. Note that what math.pow does is unrelated to what builtin pow does, and will still vary by platform.
* Revise tests to support str(<long int object>) not appending "L".Fred Drake1999-12-231-12/+12
