# Documentation

Complex numbers are an algebraic type.

For a complex number `z`

,

is a number with the magnitude of `abs`

z`z`

,
but oriented in the positive real direction, whereas

has the phase of `signum`

z`z`

, but unit magnitude.

!a :+ !a | forms a complex number from its real and imaginary rectangular components. |

mkPolar :: RealFloat a => a -> a -> Complex aSource

Form a complex number from polar components of magnitude and phase.
