LRINT(3) BSD Library Functions Manual LRINT(3)NAME
llrint, llrintf, llrintl, lrint, lrintf, lrintl — convert to integer
Math Library (libm, -lm)
llrintl(long double x);
lrintl(long double x);
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(), llrintl(), lrintf(), and lrintl() functions dif‐
fer from lrint() only in their input and output types.

These functions conform to ISO/IEC 9899:1999 (“ISO C99”).
The llrint(), llrintf(), lrint(), and lrintf() routines first appeared in
FreeBSD 5.4. The long double variants were introduced in FreeBSD 8.0.
