dxcalc(1X) dxcalc(1X) NAME dxcalc - DECwindows interface to the calculator SYNOPSIS dxcalc [options] OPTIONS Specifies the color of the window's border (color displays only). This overrides the system default defined in the Session Manager's Customize Window dialog box. Specifies the color of the window's background (color displays only). This overrides the system default defined in the Session Manager's Customize Window dialog box. Specifies the display screen where dxcalc displays its window. If the display option is not specified, dxcalc uses the display screen specified by your DISPLAY en- vironment 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 X(1X). This option is the same as the -d option. Specifies the color of the text (color displays only). This overrides the system de- fault defined in the Session Manager's Customize Window dialog box. 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 file overrides this option. Specifies the width, length, and location of the dxcalc window. If the geometry option is not specified, dxcalc uses default values. The geom- etry option has the format [widthxlength][{+-}x{+-}y]. For more infor- mation about the screen coordinate system, see X(1X). 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 appli- cation's on-line help or in this reference page. MENUS The dxcalc application contains the following menus: File Edit Mode Help Pop-up File Menu The File menu contains the following items: Saves the calculator's size and position, to use the next time you run the calculator. Restores the use of the system default values for size and position. Closes the dxcalc window. Edit Menu The Edit menu contains the following items: Undoes the last keystroke or operation. Copies the selected text onto the clipboard. Pastes in text from the clipboard. Mode Menu The Mode menu lets you select Decimal, Hexadecimal, or Octal modes. In Decimal mode, the display and accumulator must be less than 15 digits. In Hexadecimal and Octal mode, the accumulator and the display can not exceed 32 bits. Help Menu The Help menu displays information about dxcalc. Pop-up Menu To display the dxcalc pop-up menu, place the pointer at any position in the dxcalc window and click MB3. This menu contains the following items: Undo Copy Paste Exit KEY BINDINGS The dxcalc application has key bindings that allow you to use the key- board, the keypad, or function keys for all mathematical functions. Some key bindings are available only in certain modes as stated below. If a key binding is specified as Shift+F1, for example, hold down the shift key and press the F1 function key. Similarly, Ctrl+F4 means hold down the control key and press the F4 function key. Some key bindings require a sequence of two keys, for example, M + C (first type and re- lease the M key, then type and release the C key). The key bindings are: The numbers on the keypad and the numbers on the top row of keys on the keyboard map to themselves. Clears both the display and the accumulator. Maps to C (except in Hexadecimal mode) and to Shift+F1. In Hexadecimal mode, maps to Ctrl+C. Clears the display. Maps to E (except in Hexadecimal mode) and to Shift+F2. Adds the value in the display to the value in the accumulator. Maps to the plus sym- bol + on the keyboard top row and the comma , on the keypad. Subtracts the value in the display from the value in the accumulator. Maps to the hyphen on the keyboard top row and the minus sign on the keypad. Multiplies the value in the accumulator by the value in the display. Maps to the asterisk * on the keyboard top row and to PF1. Divides the value in the accumulator by the value in the display. Maps to the slash / on the keyboard bottom row and to PF2. Clears the contents of memory. Maps to the M + C key sequence and to Ctrl+F4. Subtracts the value in the display from the value in memory. Maps to the M + - key sequence and to Ctrl+F7. Adds the value in the display to the value in memory and stores the result. Maps to the M + + key sequence and to Ctrl+F6. Places the contents of the memory in the display. Maps to the M + R key sequence and to Ctrl+F5. Displays the result of the last op- eration (or series of operations). Maps to =, Enter, Do, and Return. The following functions are available in Decimal mode only. Returns the square root of the value in the display. Maps to Q and to Shift+F9. Changes the value in the display from positive to negative or from neg- ative to positive. Maps to N and to PF3. Maps to % on the keyboard top row and to PF4. Inserts a decimal point into the number in the dis- play. Maps to the period keys on the keyboard and keypad. Places the value of pi in the display. Maps to P. If the next function is sin, cos, or tan, executes the respective inverse trig function. If the next function is log or ln (natural log), returns 10 to the x or e to the x, where x is the value in the display. Maps to I and to Shift+F3. Re- turns the sine of the value in the display. (If the inverse setting is on, returns the arcsine.) The angle is in degrees, radians, or gradi- ent, according to the state of the degrees key. Maps to S and to Shift+F4. Returns the cosine of the value in the display. (If the in- verse setting is on, returns the arccosine.) The angle is in degrees, radians, or gradient, according to the state of the degrees key. Maps to O and to Shift+F5. 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 gradient, according to the state of the degrees key. Maps to T and to Shift+F6. Returns the log (base 10) of the value, x, in the display. (If the inverse setting is on, returns 10 to the x.) Maps to the L + O key sequence and to Shift+F7. Returns the natural log of the value, x, in the display. (If the inverse setting is on, returns e to x.) Maps to the L + N key sequence and to Shift+F8. 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 ^ on the keyboard top row and to Shift+F10. Switches the measurement unit for trig functions among degrees, radi- ans, and gradient. Maps to D and to Ctrl+F8. If an integer n, greater than or equal to zero, is displayed, returns the factorial of the dis- play, n*(n-1)*(n-2)...*1. Maps to the exclamation mark ! and to Ctrl+F9. Returns the reciprocal of the display. Maps to the tilde ~ on the keyboard top row and to Ctrl+F10. Returns a random number between 1 and the display. Maps to R and to Ctrl+F11.

Maps to the tilde ~ on the key- board top row and to Shift+F9. Performs a bitwise neg boolean opera- tion (complementation) on the value in the display. Maps to the ! and to Shift+F10. The following are available in Hexadecimal mode only. The numbers A through F are entered via the same keyboard letters or as follows. A: Shift+F3; B: Shift+F4; C: Shift+F5; D: Shift+F6; E: Shift+F7; F: Shift+F8. X DEFAULTS The dxcalc application uses the values in the 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 specifica- tion in the file is: [name*]resource: value Specifies the application name or the name string that restricts the resource assignment to that application or to a component of an appli- cation. If this argument is not specified, the resource assignment is globally available to all X applications. Specifies the resource. 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 identifiers, see X(1X). For dxcalc, the available class identifiers are: Calc MenuBar For dxcalc, the available name identifiers are: sqrtFontFamily KeyFont- Family The general resources listed in X(1X) 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. FILES SEE ALSO Commands: X(1X) dxcalc(1X)
