>>Have you tried shifting the decimal point? You could multiply by 100000 to shift the decimal point left for storing and then when retrieving divide back by 100000 for calculations. The number that you multiply/divide is determined by the number of significant digits that you want to maintain.

Exponent is binary, i.e. in powers of two, so your 1/10 may actually be 0.999999999... something.
