My keys (to date) are usually floating point numbers which I format like %012.7f since these numbers will never exceed 9999.

Do you need 7 decimal places of accuracy? If your application could get by with 6, you could multiply your floats by 1e6 and store them as integers--which would probably reduce space and speed things up a lot whatever DB you use.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
