Dear Yasin, you can use

round

or

floor

or

ceil

or

format

for this purpose. Also don't use condition of equality to control loop instead use some tolerance value like this:

while id1 - id2 < 1e-5
...
...
...
end

It will work better

 format long
id1=0.513709476164662
id2=0.513709476164661
id1=str2num(sprintf('%.14f',id1))
id2=str2num(sprintf('%.14f',id2))
id1==id2
