In what way do I disagree? I say that it terminates *only* if some condition holds. Obviously the condition does not hold for transcendental numbers, and so it does not terminate in that case.

In that case you should say that the *sequence of digits* is pseudorandom. Note however that it the sequence of digits of a number actually is pseudorandom it most likely is a rational number.  dik t. winter, cwi, science park 123, 1098 xg amsterdam, nederland, +31205924131 home: bovenover 215, 1025 jn amsterdam, nederland; http://www.cwi.nl/~dik/
