Nearly.  You wouldn't normaly have the fixed points as decimal as it brings
back a lot of the overhead.  Simply assign a fixed number of low order bits
for your fractional part and the rest for the integer part.  This way all
you need to do is to mask and shift in order to obtain fixed and fractional
parts.  You can then simply use normal integer math functions.
