operator * method
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 Pointint
factor. Because the
star operator always returns the same type of Point that originally called
it, passing in a double factor
on a Point<int>
causes a
runtime error in checked mode.
Implementation
Point<T> operator *(num /*T|int*/ factor) {
return Point<T>((x * factor), (y * factor));
}
