Select the required value to enter it into the calculator. The key presents a dialog showing the calculation result history, with the most recent results at the top. History and Memory Result HistoryĮach time the key is pressed, the calculation result is added to a history list. The value used for calculations is the unrounded result stored internally, and not the rounded value shown on the display. This is the same as SCI mode, except that the exponent is set to a multiple of 3. The result is displayed in the format A x 10 B, with the mantissa (A) rounded to the number of significant digits selected by. If there is not enough room, the result may be displayed with fewer decimal places. The result is displayed after rounding to the number of decimal places selected by. The number of decimal places cannot be adjusted in this mode. If its magnitude is less than 0.0001 or larger than will fit in the display, then scientific notation is used (see SCI mode below).

The result is displayed as a normal floating point value if possible. When the number of digits selected is fewer than the maximum available, the display will show the number of digits after the mode indicator e.g. This will bring up a dialog to select the number of digits, together with the current value rounded appropriately. To set the number of decimal places in FIX mode, or the number of significant digits in SCI or ENG modes, press. The display will show 'FIX', 'SCI', 'ENG' or blank to indicate the current mode. There are four display modes for calculation results. These options can be changed in the settings, under 'Display Format'. For binary, hexadecimal or octal mode, numbers are always displayed in groups of four digits. In decimal mode, the digit grouping can be selected between three-digit, four-digit or Indian grouping. Note that grouping with a space is not supported with the 7-segment display style, due to the fixed layout of the digits. Numbers can also be displayed with digit grouping, using either a comma/point or space to separate groups of digits. Numbers can be formatted on the display using either a point or a comma as the decimal separator. The display style can be selected between 7-segment, dot-matrix or standard font.

Throughout this help, functions which require shift to access are shown in orange. This feature can be disabled in Settings. Press again to cancel shift mode.Īs an alternative to using shift, the secondary function of each key can also be accessed by holding down the key. While shift is active, 'SHIFT' will be shown on the display. The key is used to access the secondary function of each key (displayed above the key in orange). The maximum exponent which can be entered is 999. Note that the exponent key means 'times 10 to the power' and it is not necessary to enter the 'times 10' yourself. To enter a number with an exponent, press then enter the exponent using the number and keys. The key clears the display ready for a new calculation. The key deletes the last digit entered and can be used to correct a number or exponent. To enter a negative number, press after entering the number. The number keys to and decimal point are used to enter numbers. Note that this help is available from within the calculator, just select Help from the main menu.
