# operator * method Null safety

Point<T> operator * (

1. num factor

)

Scale this point by `factor` as if it were a vector.

Important Note: This function accepts a `num` as its argument only so that you can scale `Point<double>` objects by an `int` factor. Because the `*` operator always returns the same type of `Point` as it is called on, passing in a double `factor` on a `Point<int>` causes a runtime error.

## Implementation

    Point<T> operator *(num /*T|int*/ factor) {
      return Point<T>((x * factor) as T, (y * factor) as T);
    }
