Exactly. Simply a mathemetical method to avoid extra work

The same here. And for that I'm grateful. Was that 7 sheep or 7i (or 7j) sheep? ZZZzzz.

Precisely! Unless you're a mathematician a complex number result probably means that you made a mistake somewhere.

To me kind of like "irrational numbers". You probably can't actually measure them to more than a few decimal places so why bother calculating them to a million? Unless you're in to that sort of thing. Each to his/her own.
