Why use it
Percentages need consistent decimals and a house treatment for negatives (often red). Cycling through your standard percentage formats applies that in a keystroke.
How consultants use it
Consistent number formatting is a basic quality signal in a model, and applying a house standard by hand is slow. Three habits apply:
- Consistent decimals: the standard number of decimal places is applied
- Negatives on standard: negative percentages follow the house treatment, e.g. red
- On the house standard: the formats come from the defined cycle
Cycling percentage formats keeps percentages consistent, negatives included.
Tips & best practices
- Select a range and cycle to the standard format.
- Set the formats to your house standard under Settings → Cycles.
- Keep formatting consistent across the whole model.
