Percentage in Text Field Properties Format

Since this field could be used in a calculation, Adobe chose to keep the value as a decimal value and make the display image appear as a percentage with the percent sign and appropriate decimal point adjustment.

If you want, you can create a text field and write all the necessary code to validate the user input for the field, and for any field that uses this field for a calculation you will have to provide the function to convert the string value to a number and adjust the decimal point.

This field is being used in a calucation.

34 (How many hours of unused sick leave did employee cash-out at time of retirement?)
x 54.50% (What percentage was employee paid for sick leave at time of retirement?)
x 27.34 (Hourly rate employee was paid for sick leave cash-out?)
--------------
$506.61 (Total value of paid sick leave at retirement)

I have my calucation in the "Total value of paid sick leave at retirement" text field under the "calculate" tab in the Text Field Properties. With Acrobat 9 Pro, they make it so much easier to do the calcualtions. So I guess what I need to know is what the necessary code should be and what tab does it go under in the Text Field Properties. I only know how to do really basic things when it comes to codes.
