LROUND(3)		   Linux Programmer's Manual		     LROUND(3)

NAME
       lround,	lroundf, lroundl, llround, llroundf, llroundl - round to near‐
       est integer, away from zero

SYNOPSIS
       #include <math.h>

       long int lround(double x);
       long int lroundf(float x);
       long int lroundl(long double x);

       long long int llround(double x);
       long long int llroundf(float x);
       long long int llroundl(long double x);

       Compile with -std=c99; link with -lm.

DESCRIPTION
       These functions round their argument  to	 the  nearest  integer	value,
       rounding	 away from zero, regardless of the current rounding direction.
       If x is infinite or NaN, or if the rounded value is outside  the	 range
       of  the return type, the numeric result is unspecified.	A domain error
       may occur if the magnitude of x is too large.

RETURN VALUE
       The rounded integer value.  Note that unlike round(3),  ceil(3),	 etc.,
       the  return  type  of  these functions differs from that of their argu‐
       ments.

ERRORS
       EDOM   The  magnitude  of  x  is	 too  large  and  (math_errhandling  &
	      MATH_ERRNO) is non-zero.

CONFORMING TO
       C99.

SEE ALSO
       ceil(3), floor(3), lrint(3), nearbyint(3), rint(3), round(3)
