General
- Every decimal shall have a precision
- The precision of the result of an operation is depended of the precision of the operands
Question to answer
- How does an operation effects the precision?
- When should be rounded? During calculation? At presentation of the value at the GUI?
- How do we handle error propagation? Should we divide as late as possible? (Each number is internally a fraction of two numbers)
Which calculations are done from the business side?
