MATLAB calculation bug in loop

for t_temp=0:1/250/1000:3/250
    Te_temp = subs(Te,t,t_temp);
    Te_temp = double(Te_temp);
    Te_array = [Te_temp Te_array];
    precent = ((t_temp)/(3/250))*100;
%     if percent>10*cnt
%         cnt=cnt+1;
        fprintf("%f%%\n",percent);
%         fprintf("%f%%\n",t_temp/(3/250)*100);
%     end
end

Hi, I have a question about calculation bug in MATLAB.

I want to check progress of the loop, so I calculate the percent separately as "percent" variable.

But the result is 0.00000 .

If I print the value which is calculated directly such as "fprintf("%f%%\n", t_temp/(3/250)*100)";,

It works!!! I don't know the difference these two statement.

Are there any other who have this problem?

use

format longg  % nothing wrong in your calculation it's scientific notation

at the very beginning of your code

see format and use appropriate notation you want

Thank you for your reply:)

@madhan ravi: rather than putting a link to a google search for format, it would be better to just put a link to the format help page itself.
