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



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.
