Hi,

In python 2.6, there have been some effort to make float formatting more consistent between platforms, which is nice. Unfortunately, there is still one corner case, for example on windows: print a -> print 'inf' print '%f' % a -> print '1.#INF' The difference being that in the second case, the formatting is done in floatformat.c (in stringobject.c), whereas in the first case, it is done in formatfloat (in floatobject.c). Shouldn't both functions be calling the same underlying implementation, to avoid those inconsistencies ?

Yes, float formatting definitely needs some rationalization.

While this isn't the exact issue discussed in http://bugs.python.org/issue3382, it is related, and Windows is the reason I had to back my fix out right before the freeze for 2.6 and 3.0. It's on my list of things to fix.

http://bugs.python.org/issue4482 might also be related, and I'll fix that, too.

If you could either add a comment to 3382 (with this test case) or open another bug and assign it to me (eric.smith), I'd appreciate it.

Happy New Year, all!

Eric.
