Yes, I meant "defining it rigorously is easy", not that the definition I gave was unique.
I wasn't saying that the use of "constant" is weird because I consider i to be a vector - personally I would think of i as just a number, C being a field in its own right. I just think it sounds funny to call a number a constant, outside a context in which we implicitly mean "constant function", e.g. stating that the derivative of a constant is zero.
Fair enough - I misunderstood your objections to the use of "constant"
Re-reading the thread, I realise that didn't actually explain my objection in the first place, other than to sneer at non-purists :-)
Yeah it's definitely a term more common in applied math. E.g. constant functions, scalars. So I'm understanding your physicists and engineers joke now. It does also sometimes get used for special numbers though, e.g. Euler-Mascheroni constant. Which probably comes from most of these special numbers coming from calculus. I assumed this was how OP was using it
