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 functions. 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
functions in each of the other modes.
Financial Mode Provides several complex financial functions.
Scientific Mode Provides many additional mathematical func‐
tions, including trigonometric 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 arithmetic precedence, then you should use
parentheses.
Internal arithmetic is now down with multi-precision floating point
numbers. Accuracy can be adjusted from zero to nine numeric places in
fixed notation, but numbers can be displayed in engineering and scien‐
tific notation as well. There is also an option to show or remove
trailing zeroes after the numeric point. The calculator reverts to sci‐
entific 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, completely clear the displayed
entry and totally reset the calculator.
There are ten memory registers. Numbers can be stored or retrieved in
these locations, and arithmetic can be performed upon register con‐
tents.
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" (deci‐
mal), 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).
Resource: /schemes/apps/gcalctool/mode
Values: Mode
Description: The initial calculator mode. Valid values are
"BASIC", "FINANCIAL", and "SCIENTIFIC".
Resource: /schemes/apps/gcalctool/showzeroes
Values: true, false (true)
Description: Whether to show trailing zeroes after the
numeric point in the display value.
Resource: /schemes/apps/gcalctool/showthousands
Values: true, false (false)
Description: Whether fixed numbers in the decimal base are
displayed with thousands separated.
Resource: /schemes/apps/gcalctool/showregisters
Values: true, false (true)
Description: Whether to display the memory register window
when Calculator starts.
Resource: /schemes/apps/gcalctool/trigtype
Values: Trig. type
Description: The initial trigonometric type. Valid values
are "DEG" (degrees), "GRAD" (grads), and
"RAD" (radians).
Any constants or functions that the user defines are also stored in the
GConf database.
OPTIONS
The following options are supported:
-a accuracy Specifies the number of digits displayed after
the numeric point. This value must be in the
range 0 to 9.
-D Enable debug mode.
-E Enable debug mode in the multiple-precision
arithmetic package.
-v Show the version number and usage information.
gnome-std-options Standard options available for use with most
GNOME applications. See gnome-std-options(5)
