display number with two decimals only if not interger

Hello,

 

I'm doing some operations with numbers and I want to display the final value in a text field as:

if the number is integer without decimals 100;200;32;15 etc

if the number is not integer with two decimals. 99.12; 23.11 etc

 

Now I'm using 

this.getField("textfield").value=Number(result).toFixed(2);

but it always displays decimals - like 100.00 etc.

 

Is there a function or format setting to accomplish this?

Thank you very much.

You can use:

this.getField("textfield").value=Number(result).toFixed(2).replace(".00", "");

    That is not even close to what you ask in your post, next time explain better what you actually need.

    Here is some simple, and very direct code to use in the Custom Format script.

     

    if(!Number.isInteger(event.value))

        event.value = util.printf("%.2f",event.value);

     

    It uses the built-in JavaScript function for testing if a number is an integer. If it is not an integer, then the number if formatted with 2 decimal places.  The correct way to format  numbers is with the "util.printf" function.

      This always shows 2 decimals. I added the code in the Custom Format script section for the textfield.

      I have a button click - on button click I set 

      this.getField("result").value = 2;

       

      The result is 2.00. maybe I'm missing something

      Where does this number come from?  If it is the result of a caculation, then it is likely to always be a decimal number, even if the result does not have any decimal places, i.e., it is never an integer. 

      So what you really want to detect is a 0 decimal value. 

       

      So do it this way. 

      if(/\.(\d+)/.test(event.value) && (Number(RegExp.$1)>0))
  event.value = util.printf("%.2f",event.value);
else
  event.value = util.printf("%d",event.value);

      When there is ". 00" at the end you can remove it.

        Can you please recommend a solution on how to do it? I'm thinking of using the split() function. Thanks.

        Try like this:

        this.getField("textfield").value = Math.round((result)*100)/100;

        EDIT: if there is more then 2 decimals it will round to 2 but if there is 1 it will show 1, if you still want to show 1 decimal as 2(100.2 as 100.20) use like this:

        this.getField("textfield").value = (Math.round((result)*100)/100).toFixed(2);
