</div>

is there an easy way to specify how many digits after the decimal flash will return in a variable. I know you can do it in a sort of complicated way like this:  
[AS]  
//say i want 3 decimal places out of number  
number = 100.12345  
number \*= 1000;  
Math.round(number);  
number /= 1000;  
[/AS]

but is there a better way, something like  
Math.roundPlaces(number, 3);  
?  
thanks

not that i know of ☹  
but this is shorter 😉

```auto

number = Math.round(number*1000)/1000;

```

```auto

function roundDecs(number, decs){
var timesBy = Math.pow(10, decs);
return Math.round(number*timesBy)/timesBy
}

```
