A More Accurate Briggs Method for the Logarithm
A new approach for computing an expression of the form
is presented that avoids the danger of
subtractive cancellation in floating point arithmetic, where
is a complex number not belonging to the closed negative
real axis and is a nonnegative integer. We also derive a
condition number for the problem. The algorithm therefore
allows highly accurate numerical calculation of using Briggs' method
