The display is formatted by setting options in the Preferences dialog, which is opened by selecting the Options -> Preferences menu option or tapping on the calculator's display area. The default number format is General, specifying numbers to be displayed in a natural format, with scientific notation used only when the number is too small or too large to fit on the display. Fixed format also displays the number in a natural format but only switches to scientific notation when the number is too large for the display (when the number is too small, it displays zero). Choosing the Scientific format will cause all numbers to be displayed using scientific notation. The Engineering format also uses scientific notation whereas the exponent is adjusted to a multiple of three.

Additionally, the number of digits that should be shown to the right of the decimal place can be specified. Selecting All causes all significant digits to be displayed (without trailing zeros, up to the limit of the display). Specifying a number for this field causes the display to show that number of digits past the decimal point including trailing zeros. If there are significant digits beyond what is being displayed, the last digit is rounded. This setting does not effect the accuracy of the calculations and is only used for displaying the results.

Pressing the button will temporarily format the display showing all significant digits. Pressing a second time, or performing any other operation, will return the format of the display to the specified setting. The round function, , will modify the internally stored number to be exactly equal to the number shown on the display. This is useful when you don't want internally stored, but not displayed, digits to be a part of ongoing calculations.

Other options in the Preferences dialog are:
