The (scheme complex) library exports procedures which are typically only useful with non-real numbers.
For more information see the R7RS Scheme Specification.
(angle z)
(imag-part x)
Return the imaginary part of complex number x.
(magnitude z)
(make-polar r phi)
Return a complex number corresponding to the given polar coordinate.
(make-rectangular x y)
Create a complex number with real component x and imaginary component y.
(real-part x)
Return the real part of complex number x.
