SYNOPSIS


.In 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
.Vt 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 representable as a
.Vt long , the expression lrint x is equivalent to (Vt longrint x) (although the former may be more efficient).

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