(∧

Open parenthesis. In RPN mode, this is stack roll up.

∨)

Close parenthesis. In RPN mode, this is stack roll down.

;

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 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.
