This issue may have been referred to in news:<[EMAIL PROTECTED]> but I didn't entirely understand the explanation. Basically I have this:
>>> a = float(6) >>> b = float('nan') >>> min(a, b) 6.0 >>> min(b, a) nan >>> max(a, b) 6.0 >>> max(b, a) nan Before I did not know what to expect, but I certainly didn't expect this. So my question is what is the min/max of a number and NaN or is it not defined (for which I would have expected either an exception to be raised or NaN returned in each case). As a corrollary would I be able to rely on the above behavior or is it subject to change (to fix a bug in min/max perhaps :-)? -- http://mail.python.org/mailman/listinfo/python-list
