Extended Summary

The logarithm of a real number may be represented by a complex number with imaginary part that is a multiple of pi*1j. Even multiples correspond with a positive real and odd multiples correspond with a negative real.

Given a logarithm of a real number x, this function returns an equivalent representation in a standard form: the log of a positive real has imaginary part 0 and the log of a negative real has imaginary part pi.
