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

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

       #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);

       Link with -lm.

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       All functions shown above:
           _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE ||
           _POSIX_C_SOURCE >= 200112L;
           or cc -std=c99

       These  functions  round  their  argument  to the nearest integer value,
       rounding away from zero, regardless of the current  rounding  direction
       (see fenv(3)).

       Note  that  unlike the round(3) and ceil(3), functions, the return type
       of these functions differs from that of their arguments.

       These functions return the rounded integer value.

       If x is a NaN or an infinity, or the rounded value is too large  to  be
       stored  in  a long (long long in the case of the ll* functions), then a
       domain error occurs, and the return value is unspecified.

       See math_error(7) for information on how to determine whether an  error
       has occurred when calling these functions.

       The following errors can occur:

       Domain error: x is a NaN or infinite, or the rounded value is too large
              An invalid floating-point exception (FE_INVALID) is raised.

       These functions do not set errno.

       These functions first appeared in glibc in version 2.1.

   Multithreading (see pthreads(7))
       The   lround(),   lroundf(),   lroundl(),  llround(),  llroundf(),  and
       llroundl() functions are thread-safe.

       C99, POSIX.1-2001.

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