SYNOPSIS


.In math.h "long long" llround "double x" "long long" llroundf "float x" "long long" llroundl "long double x" long lround "double x" long lroundf "float x" long lroundl "long double x"

DESCRIPTION

The lround function returns the integer nearest to its argument x, rounding away from zero in halfway cases. 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, lround may raise an inexact exception. When the rounded result is representable as a
.Vt long , the expression lround x is equivalent to (Vt longround x) (although the former may be more efficient).

The llround, llroundf, llroundl, lroundf and lroundl functions differ from lround only in their input and output types.
