#13451: is_close_to function does not exist

     Type:  Bugs                         |     Status:  new
Milestone:  To Be Determined             |  Component:  None
  Version:  Boost 1.66.0                 |   Severity:  Problem
 Keywords:                               |
-----------------------------------------+---------------------
 The example code for boost::math::tools::brent_find_minima
 (Brent_minimise_example.cpp) calls the function is_close_to. This code
 results in an error (Visual Studio 15.5.5) because the compiler cannot
 find the function. Neither can I:
 [[BR]]
 [[BR]]
 #include <boost/test/floating_point_comparison.hpp>
 [[BR]]
 using boost::math::fpc::is_close_to;
 [[BR]]
 [[BR]]
 The following code seems to work:
 [[BR]]
 template<typename FPT>
 [[BR]]
 inline bool
 [[BR]]
 is_close_to(FPT left, FPT right, FPT tolerance)
 [[BR]]
 {
 [[BR]]
         return boost::math::fpc::close_at_tolerance<FPT>(tolerance) (left,
 right);
 [[BR]]
 }
