Numeric Display and Entry

The display in scientific mode has a 12- or 16-digit mantissa with a 2-digit exponent. This is selectable in Preferences. The display in [Hex], [Dec], and [Oct] modes is 16 digits maximum, and in [Bin] mode, 32 digits. In the basic 4-function mode the display is either 8 or 10 digits, with no exponent. This is summarized in the table below.

   #DIGITS     Basic  Sci  Hex  Dec  Oct  Bin
   Large font    8:0  12:2   16   16   16   32
   Small font   10:0  16:2   16   16   16   32

During number entry, you can delete the last number in the display by pressing the backspace button (or its keyboard equivalent).

The [CE/C] (Clear Entry/Clear) button can be used to clear the current display if numeric entry is in progress, or to clear the calculator if a calculation has just been completed. The [AC] (All Clear) button resets the display and restores the calculator to its default condition.

The Edit menu is accessible at all times so that you can cut and paste numeric text freely to and from ProCalc.

In all modes, there are 50 levels of nested parenthesis available, and the current nesting level is shown in the display.
