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.
Resource: /schemes/apps/gcalctool/accuracy
Values: Accuracy value
Description: The number of digits displayed after the
numeric point. This value must be in the
range 0 to 9.
Resource: /schemes/apps/gcalctool/base
Values: Numeric Base
Description: The initial numeric base. Valid values are
"BIN" (binary), "OCT" (octal), "DEC"
(decimal), and "HEX" (hexadecimal).
Resource: /schemes/apps/gcalctool/display
Values: Display mode
Description: The initial display mode. Valid values are
"ENG" (engineering), "FIX" (fixed-point), and
SCI" (scientific).

Any constants or functions that the user defines are also
stored in the GConf database.
