The calculated risk does not result in a whole number. The results must be rounded to the appropriate whole number.
Instead of rounding to the nearest number, a lookup form is used to determine what the whole number value should be. The lookup table is stored on the Change Risk Ranges (CHG:ChangeRiskRanges) form. By default, the values are set up to move any non-whole number to the next highest number.
- 2.59 becomes 3
- 2.00001 becomes 3
- 3.99 becomes 4
The logic here is that no risk should be downplayed. Any risk greater than the whole number should be shown as the next risk up. So the resulting calculated risk is used to do a lookup against the Change Risk Ranges form, and the whole number value stored on the form is used as the risk.
