Are there adjectives to distinguish positive real numbers/functions depending on whether they are greater/equal/less than one? I have a nagging feeling that I already know the answer but can't remember.

I am expecting something along the lines of subunitary, unitary, or superunitary. Indeed, one source defines subunitary as "of a magnitude less than one unit", which is what I want. Yet, I have not encountered the term despite running into the concept all the time. Would you understand the meaning of these terms without an explanation?

None that you can expect your readers to know. There is "unimodular" (meaning $|a|=1$) but this is somewhat different from what you asked. – user31373 May 18 '12 at 22:19
Work with the logarithm, thereby reducing it to a previously solved case ("positive/zero/negative"). – mjqxxxx May 18 '12 at 23:04
Why do you need special terms? Just be clear. – lhf May 19 '12 at 1:59
Why use three words if one would do? – Emre May 21 '12 at 20:17

No, I would not understand the meaning of subunitary and/or superunitary without an explanation.
