Defined in header <cmath>
float       nextafter( float from, float to );		(since C++11)
double      nextafter( double from, double to );		(since C++11)
long double nextafter( long double from, long double to );		(since C++11)
float       nexttoward( float from, long double to );		(since C++11)
double      nexttoward( double from, long double to );		(since C++11)
long double nexttoward( long double from, long double to );		(since C++11)

Returns the next representable value of from in the direction of to. If from equals to to, to is returned.

[edit] Parameters

from, to

-

floating point values
