10244	Erroneous conversion from double to boost::rational<int>	akrzemi1	Jonathan Turkanis	"The documentation discusses in detail why conversion from double is not supported, but the following code works fine:

{{{
#include <iostream>
#include <boost/rational.hpp>

int main()
{
  double d = 31.82;
  boost::rational<int> r = d;
  std::cout << r << std::endl;
}
}}}

With the following result ""31/1"". It just discards the fractional part. A double is implicitly converted to int and then the implicit constructor from int is used. 

Such conversion is really confusing. Make it explicitly declared as deleted."	Bugs	new	To Be Determined	rational	Boost 1.55.0	Problem
