Using floats is a bad idea. Consider this python code:
dictionary = dict()
original = get_some_floating_point_value()
dictionary[original] = 'foo'
string_version = str(original) # this is where things head south
duplicate = float(string_version)
value = dictionary.get(duplicate)
Okay, so what is value? Is it 'foo'? Is it None?
(Yes, I can fix this. If I *know* that original is a float, then I
could use original.hex() instead of str(original).)
HTH,
