NAME

       nextafterd64(),	nextafterd128(), nextafterd32(), nexttowardd64(), nexttowardd128(), nexttowardd32() - next representable decimal floating-
       point numbers

SYNOPSIS

DESCRIPTION

       The function computes the next representable number following x in the direction toward y.  Thus, if y is less than x, returns the  largest
       representable number less than x.

       The function returns y if x equals y.

       The  function is equivalent to except that the second parameter has the widest decimal floating-point type, and the function returns y con-
       verted to the type of the function if x equals y.

       The result of the function is determined in the type of the function, without loss of range or precision in  a  floating  second  argument,
       whose type may be wider than the type of the function.

       These math functions are supported for HP-UX 11i Version 3 September 2008 Update and forward.

USAGE

       To use any of these functions, compile with the option.

       Make sure your program defines and then includes

RETURN VALUE

       If x equals y, returns y, and returns y converted to the type of x.

       If x is finite and the correct function value would overflow, these functions return according to the sign of x, and raise the overflow and
       inexact floating-point exceptions.

       If the return value is subnormal and x!=y, these functions raise the underflow and inexact floating-point exceptions.

       If x or y is NaN, these functions return NaN.

ERRORS

       If x is finite and the correct function value would overflow, these functions set to
