Python float to ratio

Question

I try get ration of variable and get unexpected result. Can somebody explain this?

>>> value = 3.2
>>> ratios = value.as_integer_ratio()
&g         


        

Answer 1

It's not 16/5 because 3.2 isn't 3.2 exactly... it's a floating point rough approximation of it... eg: 3.20000000000000017764
