Why does my rand function not seem to work?

limit = 0.3266;
s = 0;
counter = 0;
while 1
    tmp = rand;
    disp(tmp)
    if tmp == limit
        break
    end
    counter = counter + 1;
end
disp(counter);

Using tmp > limit, returns a value for counter, but if i did tmp == limit, it seems to go into an endless loop. First I thought the number 0.3266 had not been found until i wrote each randomly generated number to a file and later checked to discover that there's been more than 100 occurences of 0.3266 in about 5million counters, but the loop doesn't stop, Please is there something I'm doing wrong?

Because you are storing and displaying the numbers with only some decimals, there are more didigts, it would be weird if they match.

If you really want to do that operation, you should cast that random value to an int or something.

Thanks for your explanation, I got the idea

You will never hit 0.3266 exactly using the "rand" command.

You can use

if abs(tmp-limit) < 1e-6

or something similar in your code instead of

if tmp == limit
