So I can specify how many bits are used for integer and how | many bits are used for fractional representation. Then it should be | possible to assign a value and do basic arithmetic with an instance | of that class. The idea is that based on fixed point arithmetic | rules, each operation tracks changes of bit width. You may already be aware of this, but there is a package available that does exactly what you describe: http://fixedpoint.sourceforge.net It is not currently actively aintained, and it's quite slow, but it does work reliably, and we use it daily at my site. It might be best for all concerned if you simply took over that project, making it faster and well supported, rather than creating a competing one... Jim
