svn+ssh://pythondev@svn.python.org/python/trunk ........ r65258 | mark.dickinson | 2008-07-27 08:15:29 +0100 (Sun, 27 Jul 2008) | 4 lines Remove math.sum tests related to overflow, special values, and behaviour near the extremes of the floating-point range. (The behaviour of math.sum should be regarded as undefined in these cases.) ........ r65292 | mark.dickinson | 2008-07-29 19:45:38 +0100 (Tue, 29 Jul 2008) | 4 lines More modifications to tests for math.sum: replace the Python version of msum by a version using a different algorithm, and use the new float.fromhex method to specify test results exactly. ........ r65299 | mark.dickinson | 2008-07-30 13:01:41 +0100 (Wed, 30 Jul 2008) | 5 lines Fix special-value handling for math.sum. Also minor cleanups to the code: fix tabbing, remove trailing whitespace, and reformat to fit into 80 columns. ........ r65308 | mark.dickinson | 2008-07-30 17:20:10 +0100 (Wed, 30 Jul 2008) | 2 lines Rename math.sum to math.fsum ........ r65309 | mark.dickinson | 2008-07-30 17:25:16 +0100 (Wed, 30 Jul 2008) | 3 lines Replace math.sum with math.fsum in a couple of comments that were missed by r65308 ........ r65315 | mark.dickinson | 2008-07-30 21:23:15 +0100 (Wed, 30 Jul 2008) | 2 lines Add note about problems with math.fsum on x86 hardware. ........ r65326 | mark.dickinson | 2008-07-31 15:48:32 +0100 (Thu, 31 Jul 2008) | 2 lines Rename testSum to testFsum and move it to proper place in test_math.py ........

* :func:`~math.factorial` computes the factorial of a number.
(Contributed by Raymond Hettinger; :issue:`2138`.)
- * :func:`~math.sum` adds up the stream of numbers from an iterable,
+ * :func:`~math.fsum` adds up the stream of numbers from an iterable,
and is careful to avoid loss of precision by calculating partial sums.
