To perform a calculation with decimal fields by using JavaScript

You can perform calculations with decimal fields by using FormCalc. However, if the Limit Trailing Digits option is deselected, and you want to use JavaScript to perform a calculation with decimal fields, you must use a script. To maintain a high degree of precision, LiveCycle Designer ES stores the value of decimal fields as a string. The script indicates to the decimal field that it is a number.

For example, you have three decimal fields in your form design. The first is named a, the second b, and the third Total. You want to perform a calculation that adds a and b.

1.	If the Script Editor is not already displayed, select Window > Script Editor.

2.	(Optional) Drag the Script Editor palette bar until the palette is larger.

3.	Select the decimal field that you want to use in a calculation.

4.	Select Calculate from the Show list, JavaScript from the Language list, and Client from the Run At list.

5.	In the Script Source field, type the following script:

Total.rawValue = Number(a.rawValue) + Number (b.rawValue)

•	Total is the name of the decimal field that you want to use in a calculation.

•	a is the first decimal field.

•	b is the second decimal field.

6.	View the form in the Preview PDF tab.
