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)
66.666666666666671

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
