# vector with epsilon [closed]

if there are two points p1 and p2.and vector of both is ab ..

now if i say -1 < ab < 1 condition true than return F..

is that mean by points p1 and p2 intersect to each other...?

Points can not 'intersect'. They are either equal or they are not. If you create a vector based on points p1 and p2 then the vector will 'intersect' both points because that's what the vector was intended to do.

Plus, I don't get how a vector can be compared to a number. – GuillaumeC Nov 26 '10 at 9:51
ok if i sat ab<1 pr ab>1.. what does it mean.. is that mean by point p1 is not at pont p2. – tina Nov 27 '10 at 2:38
if i say vector ab <0.0001 where ab is a vector from point P1 and P2.. what means by ab<0.0001 and ab>-0.0001. – tina Nov 27 '10 at 3:54
