Do you want to round the value to significant digits, which will change in a loop? For e.g.
a_answer= .0215243225;
for i = 2:5
output = round(a_answer,i)
end
% You will get output
output =
0.02
output =
0.022
output =
0.0215
output =
0.02152
It's basically the same method as mentioned by John, only instead of looping on values I looped it for significant digits.

You can do that without manually adjusting the number of digits by specifying the 'significant' option in your call to round.
>> a_answer= .0215243225;
>> round(a_answer, 3, 'significant')
ans =
0.0215
>> b = pi/1000;
>> round(b, 3, 'significant')
ans =
0.00314
>> round(b, 5)
ans =
0.00314
