so we agree that a point is not a vector, and t= hose 2 should be kept as separated definitions.
we also agree that the main concern here is th= e design issue, which functions should a Point class have as=C2=A0
members, and which should b= e free-standing ones.
now the question asked, how do I take it on forward? what should I (star= t) writing?=C2=A0

@Thiago Macieir= a
floating point is= historical issue, there is no need to keep being mathematically incorrect = in year 2015.
