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.

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 setting, compile with the option.
