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.
