How to convert a very big rational number obtained into decimal form? Please See : format short is not making any difference

for i1 = 1 : max(l11,l12) s(i1) = 0 l13 = i1 for b = 1 : i1 if(l13 > l12) den(l13) = 0 end s(i1) = s(i1) + den(l13) * q(b) % l13 = l13 - 1 end if (i1 == ROMorder) break end end

Result obtained : s = [ 600000, -155160, -79517806820667188049/7036874417766400] - error part

Thank you but when i convert this vector into a polynomial again the coefficients of the polynomial are in the form of rational numbers not in decimal. Ex. - num = poly2sym(s) Result - num = 600000 - (388270541116539*z^2)/34359738368 - 155160*z - eroor part How to convert even these values into decimal form?
