/* FloatToFixed
converts a float in the range (0,1) to a fixed point 16 bit binary stored
as an unsigned integer. It converts negative numbers to zero and numbers bigger 
than one to the largest fixed point representation available. MaxNum should 
be the largest power of 2 representable in our unsigned integers.
