Description

Common Lisp defines `signum` on a non-real number as returning a complex number whose angle is the same as the angle of the argument but whose magnitude is 1. This degenerates to the standard definition for real numbers.

No change is needed to the standard version.

Fixed in revision [[27997]|]. Thanks for pointing this out!

I haven't tagged a release yet since this seems pretty trivial, so this is available only in trunk right now. It will appear in the next release though!
