## What do mean by round to decimal places

Check out below image

Flutter round number to decimal places will make use of a in-build method, .toStringAsFixed(2) will help us in getting how much fraction Digits we need after the decimal point and the last number will get round up.

Example

```var num = 15.12345;
print(num.toStringAsFixed(3));      /// ```

Here in .toStringAsFixed(3), Here 3 defines the parameter, How many decimal number you want after decimal point.

Example:

```void main(){

var n = 15.12345;
print(n.toStringAsFixed(3));  //  15.123

var x = 4.56;
print(x.toStringAsFixed(1));  //   4.6

var x1 = 4.53;
print(x1.toStringAsFixed(1));   //   4.5

var y = -1.55;
print(y.toStringAsFixed(1));    //   -1.6

var z = 10.5677;
print(z.toStringAsFixed(3));    //    10.568

var num = 10.85;
print(z.toStringAsFixed(0));    //    10

}```
