I tried computing the eigen vectors and eigen values for a 3×3 matrix, but the result is given in fractions after I used format rational. How can I change the format so as to get values in my matrix that include square root ? (i.e, sqrt(2)/2 )

Here are my codes:

`A = [3 1 1 ;1 0 2;1 2 0];>> [V,D] = eig(A)V = 0.0000 0.5774 -0.8165 0.7071 -0.5774 -0.4082 -0.7071 -0.5774 -0.4082D = -2.0000 0 0 0 1.0000 0 0 0 4.0000`
