Oh wait, I missed that.

Yes, I want numbers **less than** infinity.
Numbers greater than infinity don't exist.

Edit: Actually, I *do* mean to use \\(f(c) = [c \lt \infty]\\), since if \\(c\\) is finite, then \\(f(c) = [c \lt \infty] = \texttt{true}\\), and \\(f(\infty) = [\infty \lt \infty] = \texttt{false}\\).

Keep in mind, \\([x < y]\\) is shorthand for \\(\neg[x \geq y]\\).
