6151,"Wrong output from boot::math, cdf(complement(laplace_distribuiton<>(...))",Yan Zhou <zhouyan@…>,Paul A. Bristow,"To illustrate the bug, see the following code,


{{{

#include <boost/math/distributions/laplace.hpp>
#include <iostream>

int main ()
{
    boost::math::laplace lap(1, 1);
    std::cout << boost::math::cdf(lap, 1) << std::endl;
    std::cout << boost::math::cdf(boost::math::complement(lap, 1)) << std::endl;

    return 0;
}
}}}

The output should be two numbers sum up to 1. Instead, it print

0.5 (this is correct)
0.0676676 (this is wrong)

I have double read the boost::math documents, to make sure that I didn't misused the library. Hopefully I am not making a stupid mistake here. Otherwise, the bug looks so stupid to me that I still don't believe this is a bug in boost::math, instead I did something wrong here.",Bugs,closed,Boost 1.49.0,math,Boost 1.48.0,Problem,fixed,laplace distribution,
