Overview of decimal fields

Decimal fields are very similar to numeric fields. The following table describes the differences between decimal and numeric fields.

Field

Description

Decimal field

Displays numbers in decimal format.

You can set the maximum number of leading and trailing digits.

You can set a display pattern to restrict the formatted value with the leading and trailing digits.

You cannot specify a data format for a decimal field; it is always stored as decimal.

By default, the formatted value includes two digits following the radix character.

Numeric fields

Displays numbers in float or integer format.

You cannot set the maximum number of leading and trailing digits.

You can set a data pattern and data format (either float or integer).

The formatted value includes only two digits following the radix character.

Use the decimal field in the following cases:

•

If you want to set the number of leading or trailing digits

•

If you want the precision of decimal or integer data to be shown exactly as it is entered (by ensuring the Limit Trailing Digits option is deselected) without any rounding

For example, a field called Qty is located within a repeating subform. In the first instance of the subform, the Qty field may have the value 3, and in the second instance of the subform, the Qty field may have the value 3.123:

•

If the Limit Trailing Digits option is set to a maximum of 2, the first number is stored as 3 (because trailing 0s are removed) and the second number is stored as 3.12 (because the number is rounded).

•

If the Limit Trailing Digits option is deselected, both numbers are stored exactly as they are entered (the first number is stored as 3 and the second number is stored as 3.123).

To learn more about the options for decimal fields, see the section on numeric fields because many of the options are identical.

Note:

To use the decimal field object in an interactive form, you must have Adobe Reader 6.0.3 or later.
