This snippet based on Binet's formula combined with fast power algorithm. Four multiplications run in parallel, thus processor with four cores recommended. Bitwise operators improve divisions and multiplications by pow of 2.

Function, what calculates x^n by non-recursive basic exponentiation squaring algorithm. This method uses the bits of the exponent to determine computing powers. Generic parameter x suitable for any type what supports multiplication. I do not suppose existence of inverse operator like "/", thus parameter n must be a positive integer only. It is not difficult to define an extended variant for a type what supports division.

The random hyperharmonic series is the infinite series S = Sum(1,inf,d(i)/i^pow), where integer pow is greater than 1, and d(i) are independent, identically distributed random variables with property P(d(i)=0) = P(d(i)=1) = 0.5. Cumulative function F(x) = P(S < x) for even powers can be build by combination of analytical and numerical computations.
