Integer v float - Python
If you had f failures in s samples, what proportion failed? .6666666666 you might correctly say - but Python might not come up with that answer if you have two integer counts
>>> s = 6
>>> f = 4
And that gives:
>>> f/s
0
Will that be better if we turn it into percentages?
>>> f*100/s
66
Yes - somewhat better but still inaccurate - the real solution is to convert one of the operands into a float:
>>> f*100/float(s)
