I never had to learn any in Calculus. We usually left them in exact form for elegance and precision. Rounding was frowned upon.
Edit: "exact" meaning leaving the square root of 2 as the square root of 2 (in math symbols of course). Any rounded form with an arbitrarily long number of decimal places would probably make the teacher think you had cheated with your calculator. Incidentally, good calculators can also solve things in exact form...
