I am trying to find the intersection of n sets which contain numerical solutions to a system of equations, all of which share atleast one common solution. Due to innacuray, in one set the common solution will be s1= {400.0000145, 15.002} and in the other s2={399.999991, 15.0001} . I have tried

Intersection[ SetAccuracy[s1,m] ,SetAccuracy[s2,m] ]

with various values of m, but I get {}.

It seems to me that SetAccuracy doesn't seem to stick, since even when I redefine s1 with
s1=SetAccuracy[s1,m]

In[5546]:=
FullForm[s1]

Out[5546]//FullForm=
List[400.00001450000002`4.6021,15.00002`3.1761]

I get the full number. Any suggestions?
