Calculation Checks

Always test that a divisor is not equal to zero before dividing with it.

Example of Testing Divisor Value:

• If a calculation result field for a report or display overflows, fill it with *HIVAL, such as 999s.
• Unless specifically told not to, always half-adjust when adding together two fields of different precision levels.
