MATLAB: How do i round to two decimals without zeros at the end

rounding

Hi I just want to keed 2 decimal places without those zeros shown at the picture what do I do please I tried round

I think this might do what you want

fprintf('Dog detected at second %0.2f\n',idx(:))

MiauMiau, the numbers you are looking for are obviously different from the short format you see. Do this:

[~,idx] = min(abs(X(:,1) - 6.0018));
Y = X(idx,1);
[~,idx] = min(abs(X(:,1) - 17.9203));
fprintf('%15.15f   %15.15f\n',Y,X(idx,1))

And show us the ouput in a comment on this answer, don't add another answer!

I have a feeling you will need to set your tolerance much higher, like 10^-4.

Please read about round and about int8 and other
