Unrelated thought:  Users might be unsure if the exponent in a hexadecimal float is in decimal or in hex.

I was playing around with float.fromhex() for this thread, and the first number I tried to spell used a hex exponent because that seemed like "the obvious thing"... I figured it out quickly enough, but the actual spelling feels less obvious to me.
