Here the syms toolbox is used and if you try to print any other values than lambda then MATLAB will print the value in fractions and that is unavoidable. So if you need to know the value in decimal, then use the command "vpa()" on command window for that particular variable and it can show you the decimal value upto two decimal places. Eg, vpa(z,2)
