The argument (angle) of the complex number, normalized so that -pi < arg <= pi.
WARNING: We use the floating point atan function, so there is precision loss.
[prec=None]) |
Compute exp(z) using Fourier series.
If prec is given, compute until the nth summand
is less than
.

Complex logarithm of z with branch chosen as follows: Write z = rho*exp(i*theta) with -pi <= theta < pi. Then log(z) = log(rho) + i*theta.
WARNING: Currently the real log is computed using floats, so there is potential precision loss.
