<complex>
template<class T> complex<T> log (const complex<T>& x);
Return natural logarithm of complex
Returns the natural (base-e) logarithm of the complex number x using the principal branch, whose cuts are along the negative real axis.
The 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.
This overloads cmath's log function.
Parameters
- x
- Complex value.
Return value
Natural logarithm of x.
