Calculate percent Pdf

[heidsterv]

Hi, 

Im trying to create a script in my pdf

A (old price)  B(new price) = %discount

example : old $98  new $75 = 23.47%

Can anybody help me please?

To calculate decreasing percentage (23.47%) from 98 and 75 would be:

(98-75)/98

Thank you, how do I write it in my script so it automatically calculates?

I don't know where you want calculation or your field names so Il use example and you change it later.

As "Custom calculation script" of field where you want to show percentage use this:

var a = Number(this.getField("Text1").value);
var b = Number(this.getField("Text2").value);
event.value = (a-b)/a;

Change field names if needed.

Fantastic! Thank you so much! 🙂

If you use this script you have to check whether "a" is zero, or you'd get an error message (or a strange result). Replace the last line with this:

if (a==0) event.value = "";

else event.value = (a-b)/a;
