nexttoward(3) BSD Library Functions Manual nexttoward(3)
NAME
nexttoward
SYNOPSIS
#include <math.h>
double
nexttoward(double x, long double y);
long double
nexttowardl(long double x, long double y);
float
nexttoward(float x, long double y);
DESCRIPTION
The nexttoward() functions return the next machine representable number
from x in direction of y. It is identical to nextafter() except that the
second parameter has type long double, and the function returns y con-
verted to the type of the function if x and y are equal.
SPECIAL VALUES
nexttoward(x, y) raises the "overflow" and "inexact" floating-point
exceptions for x finite and the function value infinite.
nexttoward(x, y) raises the "underflow" and "inexact" floating-point
exceptions for the function value subnormal or zero and x not equal to y.

STANDARDS
The nexttoward() functions conform to ISO/IEC 9899:2011.
