Integers are naturally there (up to some limiting size), rationals can be handled with infinite precision as a pair of integers, quadratic irrationals can be handled by their continued fraction, algebraic numbers can be handled by manipulating their minimal polynomials, etc. Programs like Sage and Mathematica can handle e, pi, and many other common transcendentals formally, thereby maintaining infinite precision. | |
