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 converted 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.

SEE ALSO
     nextafter (3) математика (3)

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