Bug ID: 58098
Summary: wrong return value of normal_distribution::min()
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: faithandbrave at gmail dot com
In <random>(bits/random.h)'s std::normal_distribution, min() function's
implementation is follow:
/**
* @brief Returns the greatest lower bound value of the distribution.
*/
result_type
min() const
{ return std::numeric_limits<result_type>::min(); }
It means return 0.0.
But, distributuon class's min() member function returns potentially return
value by operator().
I think should return numeric_limits::lowest() or -numeric_limits::infinity().
libc++ and Boost.Random's implementation returns -numeric_limits::infinity().
