std::cauchy_distribution

Defined in header `<random>`
template< class RealType = double > class cauchy_distribution;		(since C++11)

Produces random numbers according to a Cauchy distribution (also called Lorentz distribution):

f(x; a,b) = ⎛ ⎜ ⎝ bπ ⎡ ⎢ ⎣ 1 + ⎛ ⎜ ⎝ x - a b ⎞ ⎟ ⎠ 2 ⎤ ⎥ ⎦ ⎞ ⎟ ⎠ -1

(constructor)	constructs new distribution (public member function)
reset	resets the internal state of the distribution (public member function)
Generation
operator()	generates the next random number in the distribution (public member function)
Characteristics
ab	returns the distribution parameters (public member function)
param	gets or sets the distribution parameter object (public member function)
min	returns the minimum potentially generated value (public member function)
max	returns the maximum potentially generated value (public member function)

operator==operator!=	compares two distribution objects (function)
operator<<operator>>	performs stream input and output on pseudo-random number distribution (function)
