Hello community,

I have written a Scripted field where I am getting P&L of successful trades in a field that I'll later use in a visualization (sum of P&L of successful trades).

Code in painless:

```
if(doc['Type.keyword'].value == "F")
{
    return Math.round(doc['Cont P&L'].value * 100.0)/100.0;
} else {
    return 0;
}

```

Now when I am making a visualization where I am adding all the P&L from this field. And I get this value :  
-4582.040000000001

However, I am looking at a value -4582.04.

Can you guys please help me this issue? Thanks 🙂

Hi Shalvin,

I think your problem with rounding is that your parenthesis grouping for Math.round isn't including the `/100.0`. So you're taking your value \* 100 and rounding that (rounding -458204.0000001 to -458204) and then dividing that by 100 which gives you -4582.04.

So I think this would fix it;  
`return Math.round((doc['Cont P&L'].value * 100.0)/100.0);`

of even simpler  
`return Math.round(doc['Cont P&L'].value);`

You can also use the format option in your scripted field to set the format to `1000` that would tell it to not show any decimal places or thousands separator. The advantage of only doing the formatting is that if you do a sum or average of the field then the end result might be more accurate.
