How do you round to 1 decimal place in Javascript?

My Value is 1.450 and I have to round it to 1 decimal place.

I want 1.450 = 1.5 in Javascript can any body fix this please.

You need this:

```
var mynum = 1.450,
rounded = Math.round(mynum * 10) / 10;
```

suppose you have

```
var original=28.453;
```

Then

```
var result=Math.round(original*10)/10 //returns 28.5
```

From http://www.javascriptkit.com/javatutors/round.shtml

You can also see How do you round to 1 decimal place in Javascript?

Given your fiddle, the simplest change would be:

```
result = sub.toFixed(1) + "M";
```

to:

```
result = Math.ceil(sub.toFixed(1)) + "M";
```

If you use `Math.round`

then you will get `1`

for `1.01`

, and not `1.0`

.

If you use `toFixed`

you run into rounding issues.

If you want the best of both worlds combine the two:

```
(Math.round(1.01 * 10) / 10).toFixed(1)
```

You might want to create a function for this:

```
function roundedToFixed(_float, _digits){
var rounder = Math.pow(10, _digits);
return (Math.round(_float * rounder) / rounder).toFixed(_digits);
}
```
