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

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

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.

RETURN VALUE
If x is and return x.

If x is NaN, the and functions return NaN.

ERRORS
No errors are defined.
