data Complex a :: * -> *

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.


!a :+ !a infix 6

forms a complex number from its real and imaginary rectangular components.
