	For this vector, returns its two coordinates as a number pair
bool	IsEqual (GVec2d theOther, double theLinearTolerance, double theAngularTolerance)
	Returns True if the two vectors have the same magnitude value and the same direction. The precision values are theLinearTolerance for the magnitude and theAngularTolerance for the direction.
