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

template<typename _RealType = double>

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

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