Classes | |
| class | CGAL::Rational_traits< NT > |
The class Rational_traits can be used to determine the type of the numerator and denominator of a rational number type as Quotient, Gmpq, mpq_class or leda_rational. More... | |
Functions | |
| template<typename Rational > | |
| Rational | CGAL::simplest_rational_in_interval (double d1, double d2) |
computes the rational number with the smallest denominator in the interval [d1,d2]. | |
| template<typename Rational > | |
| Rational | CGAL::to_rational (double d) |
computes the rational number that equals d. | |
| Rational CGAL::simplest_rational_in_interval | ( | double | d1, |

| ) |
#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.
CGAL::to_rational() | Rational CGAL::to_rational | ( | double | d | ) |
#include <CGAL/to_rational.h>
computes the rational number that equals d.
Computes the rational number representing a given double precision floating point number.
