NAME
       nextafter(),  nextafterf(),  nextafterl(),  nextafterw(), nextafterq(),
       nexttoward(),  nexttowardf(),  nexttowardl(),  nexttowardw(),   nextto‐
       wardq() - next representable floating-point values

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       The  function  computes	the  next representable double-precision value
       following x in the direction of y.  Thus, if y is less than x,  returns
       the largest representable floating-point number less than x.

       The function returns y if x equals y.

       The function is equivalent to except that the second parameter has type
       and the function returns y converted 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.

       is a version of it takes arguments and returns a result.

       is an version of it takes arguments and returns an result.

       is equivalent to on HP-UX systems.

       is a versions of it takes a first argument and returns a result.

       is equivalent to

       is equivalent to on HP-UX systems.

USAGE
       To  use these functions, compile either with the default option or with
       the and options.

       To use (for Integrity servers) or compile also with the option.

       Make sure your program includes Link in the math library by  specifying
       on the compiler or linker command line.

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

       If x or y is NaN, and return NaN.

       If  x  is  finite  and  the  correct function value would overflow, and
       return (equal to +INFINITY), according to the sign of x, and raise  the
       overflow exception.

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

ERRORS
       If x is finite and the correct function value would overflow,  sets  to
       [ERANGE].

   Integrity Server Only
       HP-UX  functions	 on Integrity servers do not set by default.  For set‐
       ting, compile with the option.
