Why when i convert Cell2mat than to double the values changes ?

i am having this cell array

% bsh=busdata(:,17);
bsh={'Shunt susceptance B'
0
0
0
0
0
0
0
0
0.1900000
0
0
0
0
0}

I am converting to mat with

bsh=cell2mat(bsh(2:nbus+1)); % nbus=14  to exclude first cell

and if i want to convert to double with

bsh= double(bsh);

in the 0.19000 value i get 0.189999997615814

how is this possible?

Thanks a lot !!
