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.

    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. 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. 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. 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. 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. This option makes the calculator come up with no menubar. 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.

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
Name | Class | Type | Default
postMenuBar | PostMenuBar | Boolean | True
accuracy | Accuracy | int | 2
base | Base | string | decimal
displayNotation | DisplayNotation | string | fixed
mode | Mode | string | scientific
trigType | TrigType | string | degrees

    Specifies whether the menu bar should appear or not. Specifies whether the menu bar should appear or not. 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. 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.
