Does anybody know how to round a number that is displayed? (two or three decimal places max)  
So I have:  
export function button3\_click(event) {

let A=Number($w(“#input127”).value);  
let B=Number($w(“#input128”).value);  
let C=Number($w(“#input129”).value);  
let D =Number($w(“#input130”).value);  
let Resultado5 = A_B_(1-C)+A/C  
**let** Resultado3 = Resultado5/D  
$w(“#text44”).text = Resultado3.toString();  
}  
The problem is that the result is always shown with a lot of decimal places…

@jpvac A function needs to be written to handle this.

```javascript
function RoundDecimal(num, dec){
    // in case number is less than 0
    let GrLessZero = num >= 0 ? 1 : -1;
    return (Math.round((num * Math.pow(10, dec)) + (GrLessZero * 0.0001)) 
    /Math.pow(10, dec)).toFixed(dec);
}

```

Follow links for some documentation of the functions used.

Thank you man, but how do I associate my “Resultado3” with that function?

@jpvac This is the function call for 2 decimal places:

```javascript
let Resultado3 = RoundDecimal(Resultado5/D,2);

```
