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.

                            CALCULATOR MODE
   #DIGITS         Basic  Sci   Hex  Dec  Oct  Bin

   12-digit font    8:0  12:2   16   16   16   32
   16-digit 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.

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

The Edit menu is accessible at all times so that you can cut and paste calculations freely to and from CalcWorks. Simple algebraic expressions can be pasted into CalcWorks, and the results of the calculation will appear in the display. Operations currently supported are: + (add), - (subtract), * (multiply), / (divide), ^ (exponent), % (percent), &, | (logical AND/OR - binary math modes only), parenthesis, and equals. You do not need to include an equals at the end of the expression, this is done automatically. If the calculator is in RPN mode, expression evaluation is performed using algebraic logic. You also cannot paste operations in the middle of a calculation in RPN mode. Numbers cut or pasted are formatted or interpreted in the context of the current mode (for example, numbers pasted in HEX mode are interpreted by CalcWorks as hexadecimal numbers).
