Format your calculator to four decimal places
It is a good idea to format your calculator to four decimal places. There are a number of reasons for this:
1. The CFA® institute rarely gives answers that use more than four decimal places. Answers are usually up to two decimal places.
2. When seeing four decimal places it is easy to calculate a percentage to 2 decimal places in your head, without having to manually multiply by 100 on your calculator.
