- Imagine you need to subtract one number from another using MATLAB.
- You will not be using eval for this task.
- Given two ASCII strings representing two integers X and Y.
- Each of them has only 12 or less ASCII characters.
- Each of them represents signed integers, such as '+2345'
- Please output the result of (X-Y) in a similar style.

function z = mysub(x,y)
z = num2str( str2num(x) - str2num(y) );
end
why this is not working for this code?
Nice
Hi. My code only prints out '-' for a negative number but not '+' for a positive. Can anyone help? function Z = mysub(X,Y); W = (str2num(X))-(str2num(Y)); Z = num2str(W); end
actually each of them has 14 characters or less...15 if we count the signs.
Mark Sanderson, if W > 0 Z = ['+' ...]
how about solving this problem but not using any conversion functions like num2str , str2num , str2double ...
This problem needed much larger test cases. At least beyond intmax('uint64') range. Also negative inputs were not implemented at all.
