Appropriate datatype for holding percent values?
...r potentially even into the negatives).
Treat value 1 as 100%, 0.5 as 50%, etc. This will allow any math operations to function as expected (i.e. as opposed to using value 100 as 100%).

Are there any O(1/n) algorithms?
...he numbers, minimum of time that sleep can wait, time to process arguments etc.): this limit would then be a constant lower bound so in fact the above function still has runtime O(1).
