NAME

       lrint, lrintf, lrintl, llrint, llrintf, llrintl - round to nearest integer

SYNOPSIS

       #include <math.h>

       long int lrint(double x);
       long int lrintf(float x);
       long int lrintl(long double x);

       long long int llrint(double x);
       long long int llrintf(float x);
       long long int llrintl(long double x);

DESCRIPTION

       These  functions  round	their argument to the nearest integer value, using 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.

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), lround(3), nearbyint(3), rint(3), round(3)
