Function Li(x)

In mathematics, the logarithmic integral function or integral logarithm Li(x) is a special function. It is relevant in problems of physics and has number theoretic significance. In particular, according to the Siegel-Walfisz theorem it is a very good approximation to the prime-counting function, which is defined as the number of prime numbers less than a given value x.

More about Li(x).

First enter the number of rectangles (pretty much like the precision) then the number x, separated by a space. Then you'll get the upper(largest rectangle area) and lower(smallest rectangle area) bounds of Li(x).

WARNING!
If the number of rectangles is too big (I don't know exactly how big...) the program may crash or it may take longer to execute.
