I've come to a trick : (with typedef boost::rational<mpz_class> rat)
rat x = /* ... some calculus with variable of type rat ... */ ;
x = rat(x.numerator(), x.denominator());
Well, this is'nt pretty. What's more, it implicates some operations of numbers of type mpz_class : so it takes time, and my program is greedy about it (it's a Bentley-Ottmann's algorithm on thousands of segment lines).
Any idea to avoid something that greedy ?
@Micheal Olea : honest mistake ;) Thanks for the interest.
