I feel some uncomfortableness to solve with a not mathematical method, like text processing. But it may smarter than take care of floating point, round error, etc.

hi my code works for tests 1 3 4 but not for test 2, can anyone help me?
here is my code:

function y = find_max_sigdec(x)
how_much_dec=[0]*[length(x)];
for i=1:length(x);
count=0;
while x(i)~=round(x(i))
x(i)=x(i)*10;
count=count+1;
end
how_much_dec(i)=count
end
y=max(how_much_dec)
end
