Complex numbers are an algebraic type.
For a complex number z, abs z is a number with the magnitude of z,
but oriented in the positive real direction, whereas signum z
has the phase of z, but unit magnitude.

|Extracts the real part of a complex number.
|Extracts the imaginary part of a complex number.
|Form a complex number from polar components of magnitude and phase.
|cis t is a complex value with magnitude 1
and phase t (modulo 2*pi).
|The function polar takes a complex number and
returns a (magnitude, phase) pair in canonical form:
the magnitude is nonnegative, and the phase in the range (-pi, pi];
if the magnitude is zero, then so is the phase.
|The nonnegative magnitude of a complex number.
|The phase of a complex number, in the range (-pi, pi].
If the magnitude is zero, then so is the phase.
|The conjugate of a complex number.
