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.

Rename math.sum to math.fsum

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.

Rename testSum to testFsum and move it to proper place in test_math.py
