When you look up the probability in a z-table is that the value less than or less than or equal?

For example is it $p(z<2.35)=.0094$ or is it $p(z\le 2.35)=.0094$?

And if they aren't equal then how would you calculate the other one?

I would think given any single point has 0 width that it shouldn't matter, but I am not sure.
