So Thursday was 3E?
Somehow, 76 makes more sense.
Two weeks ago I almost bought a calculator with a base 5 (pental) system on it. Not for that, but the other features. Found cheaper one, though, sans pental.
Couldn't figure out what a radix of 5 would be for, so I Gurgled it, but my Gurgle-fu is really bad.
Best thing I could think of was it was either for people with abacuses or only one hand.
