complex infinity

[Doug Gwyn (VLD/VMB)]

The mathematically natural way to complete the complex plane is with
a SINGLE point at infinity.  Thus there is no need for a direction.

Unlike the artificial inclusion of +Inf and -Inf in IEEE f.p. real
number arithmetic, the complex point at infinity has genuinely nice
properties.  IEEE f.p. was wrong to take the tack it did when it
introduced so much complexity as well as incompatibility with proper
mathematical usage.
