NAME
dtcalc - The CDE Calculator
SYNOPSIS
dtcalc [-a accuracy] [-m mode] [-b numeric_base] [-notation
display_notation] [-trig trigonometric_type] [-no_menu_bar]
[-session session_file] [-?]
DESCRIPTION
The dtcalc utility is a calculator for use within the CDE.
It provides an easy-to-use interface designed to give access
to common arithmetic and financial calculations.
The calculator is designed to operate in much the same way
as many hand-held calculators. It provides three modes of
operation: scientific, financial, and logical. The default
operation is scientific, but with the easy-to-use GUI,
changing to the modes of operation is easy. When the
operation mode is changed, a number of the keys change for
the new operations.
OPTIONS
The dtcalc utility defines a number of command-line options
that allow the user to configure how the calculator displays
itself. Command-line options have a higher precedence than
resources. By using command-line options a user can
override anything specified in a resource file.
-a <accuracy> This is the initial number of digits
displayed after the numeric point. This
value must be in the range 0 to 9. The
default value is 2.
-m <mode> This determines which mode the calculator
will display itself in. The possible
values for <mode> are: scientific,
financial, or logical. Scientific is the
default mode. Some of the calculator keys
change operations when the calculator's
mode is changed.
-b <numeric_base>
This determines which numeric base the
calculator will use when it does
calculations. There are four bases the
calculator supports: binary (base 2),
octal (base 8), decimal (base 10), or
hexadecimal (base 16). The possible
values for <numeric_base> are: binary,
octal, decimal, or hexadecimal. The
default is decimal.

dtcalc(1) UNIX System V (1 August 1995) dtcalc(1)-notation <display_notation>
This determines how the answers are to be
displayed on the calculator. The possible
values for <display_notation> are:
scientific, engineering, or fixed. The
default is fixed.
-trig <trigonometric_type>
This determines how answers are presented
when the calculator is in scientific mode.
The possible values for
<trigonometric_type> are: degrees,
radians, or gradients. The default is
degrees.
-no_menu_bar This option makes the calculator come up
with no menubar.
-session <session_file>
The dtcalc utility runs with the session
file specified in the session_file
parameter. Session files are generated as
a dtcalc session shuts down.

RESOURCES
The calculator supports a number of resources which make it
much more configurable. Following is the list of supported
resources and their default values.
Client Resource Set

the default for the numeric base the
calculator uses when it does its
calculations. The default is "decimal"
which is base 10. Possible values are:
binary (or bin): do calculations in base
2.
octal (or oct): do calculations in base 8.
decimal (or dec): do calculations in base
10.
hexadecimal (or hex): do calculations in
base 16.
Dtcalc*display:
This resource allows the user to change
the default for the way answers are
displayed on the calculator. The default
is "fixed". Possible values are:
fixed (or fix): display in fixed mode.
scientific (or sci): display in scientific
mode.
engineering (or eng): display in
engineering mode.
