round(3M)							     round(3M)

NAME
       round(), roundf(), roundl(), roundw(), roundq() - round functions

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       The  function  rounds  its  argument  to	 the nearest integral value in
       floating-point format.  An argument exactly halfway between  two	 inte‐
       gers  is	 rounded  away	from  zero, regardless of the current rounding
       direction.  Rounding away from zero also applies to the functions, and

   Integrity Server Only
       is a version of it takes a argument and returns a result.

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

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

       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.

       To  use	these  functions,  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 returns x.

       If x is NaN, returns NaN.

       may raise the inexact exception if x is non integral and finite.

ERRORS
       No errors are defined.
