_RealType a () const
_RealType b () const
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.

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

class std::cauchy_distribution< _RealType >" A cauchy_distribution random number distribution.

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