C++ Complex Library - Log

Description

It is a natural logarithm of complex and returns the natural (base-e) logarithm of the complex number x, using the principal branch, whose cuts are along the negative real axis. .

he value computed is bounded along the imaginary axis between [-i*PI,i*PI].When x is a negative real number, log(x).imag() is PI.
