Synopsis
#include <boost/math/special_functions/next.hpp>
namespace boost{ namespace math{ template <class FPT> FPT float_prior(FPT val); }} // namespaces Description - float_priorReturns the next representable value which is less than x. If x is non-finite then returns the result of a domain_error. If there is no such value less than x then returns an overflow_error. Has the same effect as nextafter(val, -std::numeric_limits<FPT>::max()); // Note most negative value -max. |
