NaN support etc.

[Andreas Beyer]

Hi,

How do I find out if NaN, infinity and alike is supported on the current 
python platform?
I could do the following:
try:
   nan = float('NaN')
   have_nan = True
except ValueError:
   have_nan = False

Is there an 'official' handle for obtaining this information?
Similar: How do I get the maximum/minimum double for current machine?

Thanks! Andreas
