The format for this field.

The PDF specification does not define how fields should be formatted. Acrobat uses a set of standard JavaScripts to perform field formatting.

This property reflects the JavaScript formatting function which is being used and the values which are being passed to it. A typical value might be:

AFNumber_Format(2, 3, 0, 0, "", true);

This defines a number format with two decimal places. For a precise understanding of the purposes of the other parameters, you will need to see the JavaScripts which come installed with Acrobat.

Other typical formatting functions are AFPercent_Format, AFSpecial_Format, AFDate_Format and AFTime_Format. Again, for full details, you should see the JavaScripts which come installed with Acrobat.
