44 * RTE Rational Approximation
46 * Given a rational number alpha with 0 < alpha < 1 and a precision d, the goal
47 * is to find positive integers p, q such that alpha - d < p/q < alpha + d, and
55 * Find best rational approximation
58 * Rational number to approximate
60 * Precision for the rational approximation
62 * Pointer to pre-allocated space where the numerator of the rational
63 * approximation will be stored when operation is successful
65 * Pointer to pre-allocated space where the denominator of the rational
66 * approximation will be stored when operation is successful
68 * 0 upon success, error code otherwise
