# operator * method

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.

Example:

    // Integer values.
    var point = const Point(10, 100) * 10; // Point(100, 1000)
    point = const Point(-10, -100) * 5; // Point(-50, -500)
    // Double values.
    var doublePoint = Point(10.0, 100.0) * 1.5; // Point(15.0, 150.0)
    // Runtime error due the invalid type cast.
    var newPoint = const Point(10, 100) * 1.5; // Throws.

## Implementation

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