This is basically if it has any interest..or else ignore... This inverts the digits. So 321 should be 123..not tested.... We only invert the ten bases, but it can be ok for others. A) 1*10^4 + 2*10^3 + 3*10^2 + 4*10^1 + 5 * 10^0 -------------------------------------------- B) 10^4 + 10^2 + 10^0 + 10^-2 + 10^-4 Divide A) by B)
