§3.1(iii) Rational Arithmetics
►Computer algebra systems use exact rational arithmetic with rational numbers , where and are multi-length integers. During the calculations common divisors are removed from the rational numbers, and the final results can be converted to decimal representations of arbitrary length. …14: 11.15 Approximations
