title: Fastest C++ Rational Number library
body: <p>I'm using <a href="http://gmplib.org/manual/C_002b_002b-Interface-Rationals.html#C_002b_002b-Interface-Rationals" rel="nofollow">GMPXX</a> wrapper of <a href="http://gmplib.org/" rel="nofollow">GMP</a> and it is not fast enough. Is it possible to find some comparison of rational number libraries' speed?</p>
  
  <p>During my calculation a very big rational number will appear with 10^100 denominator and same size numerator.</p>
  
  <p>Do you know something faster than GMP?</p>
