This situation happens due to the fact that
mod(1,1)
is not actually zero, it is really close to zero. You need to indicate a condition whether the value is under a certain tolerance or not. Change your code to the following:
function test(n)
n2=mod(n,1)
while (n2) ~= 0
if ismembertol(n2,fix(n),1e-5) || n2<1e-5
break;
else
n2 = mod((n2)*10,1);
end
end
n2;
With the above if condition, we assume the number n2 as zero if it is smaller than 1e-5.
