Worth mentioning is storing the logarithm of the number.Seen it used in a couple places. Logarithmic depth buffer is one. Yamaha DX7 is another.
That's kind of exactly what floats are. You store the log2 of the number, a bit for its sign, and in what remaining bits you have left some fixed-point scaling between adjacent powers.
I think they mean storing just an exponent instead of an exponent + mantissa. Makes multiplication much easier to implement.
