NAME
       rint(),	rintf(), rintl(), rintw(), rintq(), nearbyint(), nearbyintf(),
       nearbyintl(), nearbyintw(), nearbyintq() -  round  to  nearest  integer
       functions

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       and return the integer (represented as a floating-point number) nearest
       x according to the current rounding direction  mode.   These  functions
       meet  the  requirement  of  the IEEE-754 standard for an operation that
       rounds to integer in floating-point format.

       The two functions are identical except that raises the  inexact	excep‐
       tion if the result differs in value from the argument, while does not.

       In  the	default	 rounding direction (round to nearest), is the integer
       nearest x with the additional stipulation that  if  |−x|=1/2,  then  is
       even.  (The same statement applies to

       If  the	current	 rounding  direction  is toward negative infinity, and
       return the same value as If the current rounding	 direction  is	toward
       positive infinity, and return the same value as

       are  versions  of  and  respectively; they take a argument and return a
       result.

       and  are versions of and respectively; they take an argument and return
       an result.

       and are equivalent to and respectively 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 with the
       option.	Make sure your program includes Link in the  math  library  by
       specifying on the compiler or linker command line.

       For more information, see the at the following site:

RETURN VALUE
       If x is and return x.

       If x is NaN, the and functions return NaN.

ERRORS
       No errors are defined.
