Hello,
I'm trying to find a clean and reliable way of uncovering
information about 'extremal' values for floats on versions of Python
earlier than 2.6 (just 2.5 actually). I don't want to add a dependence
on 3rd party modules just for this purpose. e.g. For the smallest
positive float I'm using,
import platform
if platform.architecture()[0].startswith('64'):
TINY = 2.2250738585072014e-308
else:
TINY = 1.1754943508222875e-38
where I've extracted the values for TINY from numpy in IDLE,
>>> float(numpy.finfo(numpy.float32).tiny)
1.1754943508222875e-38
>>> float(numpy.finfo(numpy.float64).tiny)
2.2250738585072014e-308
>>>
I'm not 100% sure how reliable this will be across platforms. Any ideas
about the cleanest, reliable way of uncovering this type of information?
(I can always invoke numpy, or use Python 2.6, on my home machine and
hardcode the retrieved values, but I need the code to run on 2.5 without
3rd part dependencies.) Cheers.
Duncan
