This comes down to user options of representations.  The user selects 
the format for floating point and the format for currency.  The two 
have separate formats because non-currency floating point is likely to 
have different representation.  The hardest part is knowing which 
format to use when representing the data to the user; i.e. is this 
number representing currency or non-currency.

When it comes to accounting systems, floating numbers should be avoided 
and all data should be stored and processed as integers to avoid 
rounding issues while processing.  Only at the time of representation 
do we present the fractions by dividing by the most significant 
fraction (e.g. 100).  At the time of input we multiply by the most 
significant fraction and round as necessary.  This also has a benefit 
of processing faster as integer processing is faster than decimal
