Scientific Number Formatting

ProCalc offers several formatting options for displaying numbers in scientific mode. The following functions effect number formatting...

  [flo]  Automatic floating point notation - automatically uses either scientific or decimal notation, whichever results in the highest accuracy in the display.

  [sci]  Scientific notation - mantissa with exponent (exponent always displayed).

  [eng]  Engineering notation - same as scientific notation except exponent is always a multiple of three. Useful in dealing with metric measurements where values are commonly powers of three.

  [dec]  Decimal notation - mantissa only, no exponent.

  [fix]  Fix decimal point - press this button followed by a number 0-9 to set the number of decimal places to be shown in the display. To reset the decimal point back to a floating decimal point, press the [fix] button a second time instead of pressing 0-9, ie. press [fix] twice in succession.

NOTE:  if you select the [fix] button with the control key as opposed to pressing the [2nd] button first, you must continue holding the control key while you press the number button. Otherwise, the [2nd] and [fix] buttons will become deselected as soon as you release the control key, and the function will be deactivated.

The display format can also be set from the Number Format dialog, available in the Options menu (see “Number Format Dialog”).
