LRINT(3)	       FreeBSD Library Functions Manual		      LRINT(3)

NAME
     llrint, llrintf, lrint, lrintf -- convert to integer

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     long long
     llrint(double x);

     long long
     llrintf(float x);

     long
     lrint(double x);

     long
     lrintf(float x);

DESCRIPTION
     The lrint() function returns the integer nearest to its argument x
     according to the current rounding mode.  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,
     lrint() raises an inexact exception.  When	the rounded result is repre-
     sentable as a long, the expression	lrint(x) is equivalent to
     (long)rint(x) (although the former	may be more efficient).

     The llrint(), llrintf(), and lrintf() functions differ from lrint() only
     in	their input and	output types.

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

STANDARDS
     The llrint(), llrintf(), lrint(), and lrintf() functions conform to
     ISO/IEC 9899:1999 (``ISO C99'').

HISTORY
     These routines first appeared in FreeBSD 5.4.
