Advancing a floating-point Value by a Specific Representation Distance (ULP) float

Function float_advance advances a floating-point number by a specified number of ULP.

#include <boost/math/special_functions/next.hpp>

namespace boost{ namespace math{

template <class FPT>
FPT float_advance(FPT val, int distance);

}} // namespaces

Returns a floating-point number r such that float_distance(val, r) == distance.
