Name
       dxcalc - DECwindows interface to the calculator

Syntax
       dxcalc [ options ]

Description
       The  dxcalc command displays a 27-function calculator with one memory location that is always visible.  The dxcalc calculator has a maximum
       display of 15 digits.

       To press a button displayed in the dxcalc window, click on it with MB1 (the left mouse button, unless you have redefined it).  In addition,
       you  can  enter	numbers by typing them in from the keyboard.  To perform a function from the keyboard, check the key binding listed in the
       application's on-line help or in this reference page.

Options
       -bd color	   Specifies the color of the window's border (color displays only).  The default is specified by  means  of  the  Session
			   Manager's Customize Windows dialog box.

       -bg color	   Specifies the color of the window's background (color displays only).  The default is specified by means of the Session
			   Manager's Customize Windows dialog box.

       -d dispname	   Specifies the display screen on which dxcalc displays its window.  If the display option is not specified, dxcalc  uses
			   the	display screen specified by your DISPLAY environment variable.	The display option has the format hostname:number.
			   Using two colons (::) instead of one colon (:) indicates that DECnet is to be used for transport.  The default  is  :0.
			   For more information, see

       -display dispname   This option is the same as the -d option.

       -fg color	   Specifies the color of the text (color displays only).  The default is specified by means of the Session Manager's Cus-
			   tomize Window dialog box.

       -fn font 	   Specifies the font for calculator menus.  (Key fonts are automatically scaled to match the  size  of  the  calculator.)
			   The default font is menu12.	A  font value specified in the .Xdefaults file overrides this option.

       -geometry	   Specifies  the  width, length, and location of the dxcalc window.  If the geometry option is not specified, dxcalc uses
			   default values.  The geometry option has the format [widthxlength][{+-}x{+-}y].  For more information about the  screen
			   coordinate system, see

Key Bindings
       The dxcalc application has a specific set of key bindings that allow you to use the keypad for all mathematical	functions.   The  built-in
       key bindings are as follows:

       numbers		   The numbers on the keypad and the numbers in the number line map to themselves.

       c		   Clears both the display and the accumulator. Maps to the C key and the F1 key.

       ce		   Clears the display. Maps to the E key and the F2 key.

       Square root	   Returns the square root of the value in the display. Maps to the Q keyboard key and the PF2 numeric keypad key.

       +		   Adds  the  value in the display to the value in the accumulator. Maps to the plus symbol (+) in the number line and the
			   comma key (,) in the keypad.

       -		   Subtracts the value in the display from the value in the accumulator.  Maps to the minus sign (-) in  the  number  line
			   and the minus sign in the keypad.

       Multiplication	   Multiplies the value in the accumulator by the value in the display.  Maps to the asterisk (*) and to the PF3 key.

       Division 	   Divides the value in the accumulator by the value in the display. Maps to the slash (/) key on the keyboard and the PF1
			   key in the keypad.

       Negation 	   Changes the value in the display from positive to negative or from negative to positive. Maps to the n key.

       Percent		   Maps to the percent (%) keyboard key and the PF4 keypad key.

       Memory clear	   Clears the contents of memory. Maps to the m key/c key sequence and to the F17 key.

       Memory minus	   Subtracts the value in the display from the value in memory. Maps to the m key/- key sequence and to the F18 key.

       Memory plus	   Adds the value in the display to the value in memory and stores the result. Maps to the m key/plus (+) key sequence and
			   to the F19 keypad key.

       Memory recall	   Places the contents of the memory in the display.  Maps to the m key/r key sequence and to the F20 key.

       Equals		   Displays the result of the last operation (or series of operations).  Maps to the Enter, Do, and Return keys.

       Decimal Point	   Inserts a decimal point into the number in the display.  Maps to the period keys on the keyboard and keypad.

       PI		   Places the value for PI in the display. Maps to the p keyboard key.

       Inverse		   Inverts the next operation.	Maps to the i and F3 keys.

       Sine		   Returns  the  sine  of the value in the display.  (If the inverse setting is on, returns the arcsine.)  The angle is in
			   degrees, radians, or gradients, according to the state of the degrees key. Maps to the s and F4 keys.

       Cosine		   Returns the cosine of the value in the display. (If the inverse setting is on, returns the arccosine.) The angle is	in
			   degrees, radians, or gradients, according to the state of the degrees key.  Maps to the o and F5 keys.

       Tangent		   Returns  the  tangent of the value in the display. (If the inverse setting is on, returns the arctangent.) The angle is
			   in degrees, radians, or gradients, according to the state of the degrees key.  Maps to the t and F6 keys.

       Log based 10	   Returns the log (base 10) of the value in the display.  (If the inverse setting is on, returns 10 to x.) Maps to the  l
			   key/o key sequence and to the F7 key.

       Natural log	   Returns  the  natural  log  of  the	display.  (If the inverse setting is on, returns e to x.) Maps to the l key/n  key
			   sequence and to the F8 key.

       y to the x	   Returns the value in the accumulator raised to the power of the value in the display. (If the inverse  setting  is  on,
			   returns y to the minus x.)  Maps to the circumflex (^) and F10 keys.

       Degrees		   Switches the measurement unit for trig functions among degrees, radians, and gradients. Maps to the d and F11 keys.

       Factorial	   Returns the factorial of the display (n*(n-1)*(n-2)...*1).  Maps to the exclamation mark (!) and F12 keys.

       1 over x 	   Returns the reciprocal of the display. Maps to the tilde (~) and F13 keys.

       Random number	   Returns a random number between 1 and the display. Maps to the r and F14 keys.

X Defaults
       The  dxcalc application uses the values in the .Xdefaults file when you logged in and uses the appropriate resource specification values to
       customize the appearance of the dxcalc window.  The format for a resource specification in the .Xdefaults file is:

       [name*]resource:  value

       name	 Specifies the application name or the name string that restricts the resource assignment to that application or to a component of
		 an application.  If this argument is not specified, the resource assignment is globally available to all X applications.

       resource  Specifies the resource.

       value	 Specifies the value that is to be assigned to the resource.

       Because	each  toolkit-based application can consist of a combination of widgets (for example, push buttons and a scroll bar), you can form
       the name string by adding widget class and name identifiers to the string.  For further information about adding  class	and  name  identi-
       fiers, see

       For dxcalc, the available class identifiers are:
       Calc
       MenuBar

       For dxcalc, the available name identifiers are:
       sqrtFontFamily
       KeyFontFamily

       The general resources listed in apply to dxcalc.

       The fonts used by dxcalc are specified by an asterisk (*).  This is done so that a font family is chosen instead of a particular font.  The
       asterisk (*) is a wildcard character that matches all font sizes.
