LROUND(3)		 BSD Library Functions Manual		     LROUND(3)

NAME
     llround, llroundf,	llroundl, lround, lroundf, lroundl -- convert to near-
     est integral value

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     long long
     llround(double x);

     long long
     llroundf(float x);

     long long
     llroundl(long double x);

     long
     lround(double x);

     long
     lroundf(float x);

     long
     lroundl(long double x);

DESCRIPTION
     The lround() function returns the integer nearest to its argument x,
     rounding away from	zero in	halfway	cases.	If the rounded result is too
     large to be represented as	a long value, an invalid exception is raised
     and the return value is undefined.	 Otherwise, if x is not	an integer,
     lround() may raise	an inexact exception.  When the	rounded	result is rep-
     resentable	as a long, the expression lround(x) is equivalent to
     (long)round(x) (although the former may be	more efficient).

     The llround(), llroundf(),	llroundl(), lroundf() and lroundl() functions
     differ from lround() only in their	input and output types.

SEE ALSO
     lrint(3), math(3),	rint(3), round(3)

STANDARDS
     The llround(), llroundf(),	llroundl(), lround(), lroundf(), and lroundl()
     functions conform to ISO/IEC 9899:1999 ("ISO C99").

HISTORY
     The float and double versions of these routines first appeared in
     FreeBSD 5.4.  The long double versions appeared in	FreeBSD	6.0.
