Limit of p value from multcompare?

(I'm having exactly the same question as this one on Stack Exchange, so I'm quoting it verbatim as follows)
It seems to me that MATLAB multcompare cannot output any p value (for pairwise comparison) smaller than 9.56061674273201e-10.
To confirm this, I did
y = [ones(100,1) 2*ones(100,1) 3*ones(100,1)];
[p,tbl,stats] = anova1(y);
[c,~,~,gnames] = multcompare(stats);
p = c(:,6)
and got p values for the three pairwise comparisons
p =
9.56061674273201e-10
9.56061674273201e-10
9.56061674273201e-10
Why is there this limit in MATLAB? How should I report my p values then? It looks strange to report exactly same values for several different tests.
