You can alter how numbers are displayed, including switching between decimal and scientific notation and display mode lets you change between displayingan improper fraction or a mixed number in the first instance.

#### One of the best features of the HP10s+ is that if you are working with decimal numbers then you will get a decimal answer in the first instance.

The fraction button enables you to switch this to a fraction answer if required. The reverse is also true. Input fractions or mixed numbers and you get a fraction (or mixed number) answer in the first instance.

The percentage button is a little trickier. It is best to input a percentage sign at the end of your percentage calculation to get the correct answer. This may be due to the % function being coupled with the equals button.
