When writing tasks for statistics exams, I try to avoid non-terminal intermediate results. Students might round them and arrive at a final result that might be slightly different from the true value. Although the exam package supports a tolerance for checking the result, this could be problematic. To check if a number is non-terminal, I calculate a fraction representation and check if the denominator can be expressed by 2^p 5^q.
@Enrico: When I started developing assignments a few years ago, I was not familiar with gmp. :(
