NAME
     gnome-calculator, gcalctool - perform basic, financial,  and
     scientific calculations

SYNOPSIS
     gnome-calculator | gcalctool [-a accuracy]  [-D]  [-E]  [-v]
     [gnome-std-options]

DESCRIPTION
     Gnome calculator  is  a  desktop  calculator.  It  has  been
     designed  to  be used with either the mouse or the keyboard.
     It is visually similar to a lot of hand-held calculators.

     Calculator has the following modes:

     Basic Mode              Provides standard  calculator  func-
                             tions.  You  can store numbers in 10
                             different  memory   registers,   and
                             easily   retrieve  and  replace  the
                             numbers  in  the  memory  registers.
                             Basic  Mode is the default mode. You
                             can use all of the Basic Mode  func-
                             tions in each of the other modes.



     Financial Mode          Provides several  complex  financial
                             functions.



     Scientific Mode         Provides many additional  mathemati-
                             cal    functions,   including   tri-
                             gonometric  and  logical  functions.
                             You  can  also  store your own func-
                             tions and constants,  when  you  use
                             Scientific Mode.



EXTENDED DESCRIPTION
     Some of the calculator keys have menu marks, this  indicates
     that there is a menu associated with that key.

     One of the most important things to  remember  about  gnome-
     calculator  is  that calculations are performed from left to
     right, with no arithmetic precedence.  If  you  need  arith-
     metic precedence, then you should use parentheses.

     Internal arithmetic is now down with multi-precision  float-
     ing  point  numbers.   Accuracy can be adjusted from zero to
     nine numeric places in fixed notation, but  numbers  can  be

     displayed  in  engineering  and scientific notation as well.
     There is also an option to show or  remove  trailing  zeroes
     after  the  numeric  point. The calculator reverts to scien-
     tific notation when the number is larger  than  the  display
     would  allow  in fixed notation. In the scientific mode, the
     base of operation can  be  changed  between  binary,  octal,
     decimal and hexidecimal.  Numbers are initially displayed in
     fixed notation to nine numeric places, with trailing  zeroes
     removed, in the decimal base.

     You can use the Copy and Paste functions in conjunction with
     the numeric display to store or retrieve characters from the
     clipboard. You can also remove the last digit entered,  com-
     pletely clear the displayed entry and totally reset the cal-
     culator.

     There are ten memory registers. Numbers  can  be  stored  or
     retrieved  in  these  locations,  and arithmetic can be per-
     formed upon register contents.

     Context sensitive help is also available. Control-F1 toggles
     whether  a tooltip is displayed for the item which currently
     has focus.

     On startup,  Calculator  uses  the  following  configuration
     resources stored in a GConf database.

     Values:        Accuracy value
