The way I understand the storage of floating point numbers: FLOAT is stored as INTEGER (precision 9, scale 0) with the scale (stored separately) depending on the position of the decimal point. DOUBLE PRECISION is stored as BIGINT (18,0) with scale depending on the position of the decimal point. So (as I understand), floating point and fixed point numbers are stored in the same manner. The difference - understood by the engine - is that the *accuracy* of floating point numbers is reduced as the scale increases. The *accuracy* of the last two digits is always unreliable; hence, the more the decimal point moves to the right, the less accurate the number. This assumption does need confirmation or correction, though. The correctness of the statement aside, is your question about how to translate the words "precision" and "scale"? Possibly Thomas can help with that, as he did the German translations of quite a few of the earlier documents and often writes articles for German publications.
