Configuring the Numeric Data Display
Configure the Numeric Data Display according to the following
table:
Field Meaning
Name
Assign a name, up to 15 characters, to document the object for
printed reports. This increases the application’s size by 1 byte
per character.
Fill Left With Choose whether the left portion of the display will be filled with
zeroes or blank spaces when fewer than the maximum number
of digits are displayed.
Number of Digits Specify the number of digits to display, up to a maximum of 16.
Keep in mind that a decimal point and minus sign each take one
digit.
At runtime, if the value can’t be displayed within the number of
digits specified for the object, a string of asterisks (*) is
displayed.
Decimal Display How you configure the decimal display and polarity determines
the appearance and behavior of the Numeric Data Display. (See
the examples before this table.) The configuration also
determines the tags or expressions you must assign. Each
Numeric Data Display can have only one configuration.
Disabled—Select this item if you don’t want any decimal point
displayed. If the Displayed Value control contains a decimal
point, it will be rounded off.
