MATLAB: How to find mean gray level value

You are trying to use an sprintf() %d format to print a non-integer value. When you do that, sprintf() uses %e format instead. If you want to print out in floating point, code a %e or %f or %g format.

Remember that the mean of integral values need not be integral itself. For example the mean of 1 and 2 is not going to be an integer.

uiwait(helpdlg(message));
