RTE Rational Approximation
Given a rational number alpha with 0 < alpha < 1 and a precision d, the goal is to find positive integers p, q such that alpha - d < p/q < alpha + d, and q is minimal.

|alpha||Rational number to approximate|
|d||Precision for the rational approximation|
|p||Pointer to pre-allocated space where the numerator of the rational approximation will be stored when operation is successful|
|q||Pointer to pre-allocated space where the denominator of the rational approximation will be stored when operation is successful|
