complex

Complex numbers arise as solutions to quadratic equations whose graph does not intersect the x axis. Their literal syntax is covered in Complex number syntax.

Complex numbers can be taken apart:

real-part ( z -- x )

imaginary-part ( z -- y )

>rect ( z -- x y )

Complex numbers can be constructed from real numbers:

rect> ( x y -- z )
