### Part 3: Tips and Tricks

1. Use ROUNDUP When You Need Optimistic Estimates: If you’re in a situation where you need to provide an optimistic estimate, ROUNDUP is your go-to function.
2. Be Mindful of Negative `num_digits`: When you use a negative number for `num_digits`, you’re rounding up to the left of the decimal point. Make sure this is what you intend.
3. Combine with Other Functions: ROUNDUP can be nested with other Excel functions for more complex calculations.
