#include <CGAL/simplest_rational_in_interval.h>
computes the rational number with the smallest denominator in the interval [d1,d2]
.
Computes the simplest rational number in an interval of two double
values.
Implementation
See Knuth, "Seminumerical algorithms", page 654, answer to exercise 4.53-39.
