# Round to the nearest decimal

If we need round to the nearest whole number, we can use the `Math.round()`

function to return this:

```
Math.round(1.34234); //returns 1
```

However what if we need to round to a decimal place? For example 0.5.

The following function can be used to do just that, and the logic itself can be adapted to be used for other languages too (C#, SQL etc).

```
function roundToMultiple(value, multiple){
var t = (1/multiple);
return (Math.round(value*t)/t).toFixed(2);
}
```

This can then be used like so:

```
roundToMultiple(1.34234, 0.5); //returns 1.50
roundToMultiple(1.34234, 0.25); //returns 1.25
roundToMultiple(1.34234, 0.1); //returns 1.30
roundToMultiple(1.34234, 0.05); //returns 1.35
```

It can also be used to round to values greater than 1:

```
roundToMultiple(25.3423423, 4); //returns 24.00
```
