towardd128(), nexttowardd32() - next representable decimal floating-
point numbers
SYNOPSISDESCRIPTION
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
Link in the math library by specifying or on the linking command line.

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

gramming language C to support decimal floating-point arithmetic".
