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

RETURN VALUES

The llrint, llrintf, llrintl, lrint, lrintf, and lrintl functions return the integer nearest to their argument x according to the current rounding mode. If the rounded result is too large to be represented as a long long or long value, respectively, the return value is undefined.
