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 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.
