| # Miscellaneous Keys
> Miscellaneous keys and functions are listed in alphabetical order below. ## (∧ Open parenthesis. In RPN mode, this is stack roll up. ## ∨) Close parenthesis. In RPN mode, this is stack roll down. ## ; (Separator) Dual purpose separator key used to enter two values. This key can either be used to separate between real and imaginary components of a complex number input, or used to enter list data value pairs when used in conjunction with the [DAT] key. ## . (Decimal) Decimal point input key. Note that DreamCalc can be configured to display numbers using a comma decimal separator, however, the key graphic remains unchanged. ## AC All Clear. Clears the input expression and resets the calculator error state. In RPN mode, the stack is cleared. ## Ans Recalls the result of when [ENTER] was last pressed. In RPN mode, this functions acts as "LstX". ## CLMEM Clear Memory. Separate areas of memory may be cleared individually by selecting from the on-screen menu. ## CONST Constant shift key—provides access to a sub-set of natural physical constants from the main keypad. You will find constant abbreviations shown above the keys. Example:
>     [CONST] [ENTER]
>     Displays: 2.71... (Natural Number e)
> ## COPY Copies the display value to the clipboard. You can also use CTRL-C. The value is copied using your PC's regional setting for the decimal point. If you wish to copy the input expression string, press CTRL-E instead. ## DEL Delete or backspace. Once the input digits have been exhausted, pressing [DEL] will backspace through the entire expression input. DEL can also be used to step back from an error condition. ## DRGC DRGC allows the input value to be converted to the units designated by the calculator's current angle mode. Example: Sine of 45 degrees in radians mode. Put the calculator into the radian mode by selecting Modes->Angle Mode->Radians. Now key in:
>     [sin]
>     45
>     [DRGC] and select Deg
>     [ENTER]
>     Displays: 0.70710678118654752
## EEX Exponent input. Puts the calculator into exponent input mode. ## ENTER In algebraic modes, this key is "equals". In RPN mode, ENTER pushes the display value up the stack. ## M- Subtracts the display value from the consecutive MEM register. ## M+ Adds the display value from the consecutive MEM register. ## MODE Provides on-screen access to the calculator's mathematical configuration. The key may be pressed multiple times to page through menu screens. ## OFF Power off—acts like the window's caption bar [X] button. ## PASTE Paste the value held in the Windows clipboard into the calculator. The clipboard value may hold a complex number, and is translated using your PC's regional setting for decimal point and thousand separators. Alternatively, press CTRL-V. ## SHIFT Shift key—provides access to secondary functions labeled above the keys. ## S-MODE Statistical mode change key. Allows convenient access to change the statistical mode via the keypad. ## STO Store memory key. [STO] can be pressed in conjunction with keys labeled A - F, MEM and numeric keys 0 - 9, to store the current display value in one of the calculator's memory registers. ## RCL Recall memory key. [RCL] can be pressed in conjunction with keys labeled A - F, MEM and numeric keys 0 - 9, to recall value from one of the calculator's memory registers. ## Rnd Rounds the display value internally to the precision used in the numeric display. Rnd is particularly useful when in fixed precision modes. ## X⇔Y This key is primarily intended for use in RPN mode, and exchanges the values in the X and Y stack registers. Although not as useful in algebraic modes, it may be used to exchange values either side of a binary function. See also: General Math Functions |
