Exact, inexact, and mixed complex number representations: MIT, Gambit, Chibi, Mosh, STklos.

Exact and inexact complex number representations only (mixed complex numbers become inexact): Racket, Chicken with the numbers egg, Scheme48/scsh, Kawa, Chez, Vicare, Larceny, Ypsilon, IronScheme.

Inexact complex number representations only: Gauche, Guile, SISC, SCM, KSi, Scheme 7, UMB.

No complex numbers: plain Chicken, Bigloo, Ikarus, NexJ, SigScheme, Shoe, TinyScheme, Scheme 9, Dream, RScheme, BDC, XLisp, Rep, Schemik, Elk, VX, Oaklisp, Owl Lisp.
