WebBinary splitting is a general purpose technique for speeding up this sort of calculation. What it does is convert the sum of the individual fractions into one giant fraction. ... These are using initialising variables with the mpz … Given a series $${\displaystyle S(a,b)=\sum _{n=a}^{b}{\frac {p_{n}}{q_{n}}}}$$ where pn and qn are integers, the goal of binary splitting is to compute integers P(a, b) and Q(a, b) such that $${\displaystyle S(a,b)={\frac {P(a,b)}{Q(a,b)}}.}$$ The splitting consists of setting m = [(a + b)/2] and recursively computing … See more In mathematics, binary splitting is a technique for speeding up numerical evaluation of many types of series with rational terms. In particular, it can be used to evaluate hypergeometric series at rational points. See more Binary splitting requires more memory than direct term-by-term summation, but is asymptotically faster since the sizes of all occurring subproducts are reduced. Additionally, whereas the most naive evaluation scheme for a rational series uses a full … See more
