I want to input this fractions i.e. 1/2+1/3.. How can i get answer in same format i.e. in fractions?

>> format rat
>> 1/2+1/3
ans =
       5/6     
>> format short
>> 1/2+1/3
ans =
    0.8333
>>

Note that format rat may not give you the answer you expect once the numerator and denominator get too large.

N = 1e8;
format rat
X = (N-2^20)/N

X = 
    1038/1049  

format longg
X

X = 
                0.98951424

y = 1038/1049

y = 
         0.989513822688275

Close, but not quite right.

If you wanted more control you could use the rat function to compute the numerator and denominator (perhaps with a tolerance) or use Symbolic Math Toolbox.

NS = sym(N);
XS = (NS-2^20)/NS

XS = 

[numeratorS, denominatorS] = numden(XS)

numeratorS = 

386529

denominatorS = 

390625

[numerator1, denominator1] = rat(X) % Default tolerance

numerator1 = 
        1038

denominator1 = 
        1049

[numerator2, denominator2] = rat(X, 0) % Tolerance of 0

numerator2 = 
      386529

denominator2 = 
      390625

I do not understand how this solves the problem posted by the user?
