Everyone trusts the logarithm until it goes complex. We’re taught that log(xy)=log(x)+log(y), and it works beautifully… until one day, you try it with negative numbers and suddenly log(-1)=iπ=i(π+2π), ...

It is well established the complex exponential and logarithm are multivalued functions, both failing to maintain most identities originally valid over the positive integers domain. Moreover the ...

This repository provides Fortran, MATLAB, and Python implementations for computing the Riemann zeta function zeta(s), its derivative zeta'(s), and the logarithm of ...
