       result_type max () const
           Returns the least upper bound value of the distribution.
       result_type min () const
           Returns the greatest lower bound value of the distribution.
       template<typename _UniformRandomNumberGenerator > result_type operator() (_UniformRandomNumberGenerator
           &__urng)
           Generating functions.
       template<typename _UniformRandomNumberGenerator > result_type operator() (_UniformRandomNumberGenerator
           &__urng, const param_type &__p)
       param_type param () const
           Returns the parameter set of the distribution.
       void param (const param_type &__param)
           Sets the parameter set of the distribution.
       void reset ()
           Resets the distribution state.

   Friends
       bool operator== (const cauchy_distribution &__d1, const cauchy_distribution &__d2)
           Return true if two Cauchy distributions have the same parameters.

Detailed Description

   template<typename _RealType = double>
       class std::cauchy_distribution< _RealType >" A cauchy_distribution random number distribution.

       The formula for the normal probability mass function is $p(x|a,b) = (i
       b (1 + (ac{x-a}{b})^2))^{-1}$
