Description
Computes the remainder of each element of vector
a
, with respect to the corresponding elements of vector
b
: compute the values of
n
such that
n
=
a
i
-
n
*
b
i
where
n
is the integer nearest to the exact value of
a
i
/
b
i
. If two integers are equally close to
a
i
/
b
i
,
n
is the even one. If
n
is zero, it has the same sign as
a
i
.
