Nope. It was known already to Euklid (300 before christ) that the real number sqrt(2) can _not_ be represented as ratio of two integers. Of course, sqrt(2) is not transcendental because it is a zero of x^2 - 2, a polynomial with integer coefficients. Andre -- The only person who always got his work done by Friday was Robinson Crusoe
