dtcalc -- The CDE Calculator
dtcalc [-a accuracy] [-m mode]
[-b numeric_base] [-notation display_notation] [-trig trigonometric_type]
[-no_menu_bar] [-session session_file] [-?]
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.
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.
- -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.
- -?
- This
prints out the usage message.
The calculator supports a number
of resources which make it much more configurable. Following is the list
of supported resources and their default values.
| Name |
| postMenuBar |

| base |
| displayNotation |

| trigType |
- Dtcalc*postMenuBar:
- Specifies
whether the menu bar should appear or not.
- Dtcalc*accuracy:
- Specifies whether
the menu bar should appear or not.
- Dtcalc*base:
- This resource allows the
user to change 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.
- /usr/dt/bin/dtcalc
- This
is the executable for the CDE Calculator.
- /usr/dt/app-defaults/<LANG>/Dtcalc
- This
file includes the application defaults for the CDE Calculator.
