## operator<<() [1/3]

template<typename _RealType, typename _CharT, typename _Traits>

std::basic_ostream< _CharT, _Traits > & std::operator<< | ( | std::basic_ostream< _CharT, _Traits > & | __os,
|  | const std::exponential_distribution< _RealType > & | __x )

Inserts a exponential_distribution random number distribution `__x` into the output stream `__os`.

Parameters

  __os | An output stream.
  __x | A exponential_distribution random number distribution.

Returns
  The output stream with the state of `__x` inserted or in an error state.
