</p><p>There are four generalized functions in the <numeric> header
that follow the same conventions as those in <algorithm>. Each
of them is overloaded: one signature for common default operations,
and a second for fully general operations. Their names are
self-explanatory to anyone who works with numerics on a regular basis:

and multiplies all the members of the array; here we must obviously
use 1 as a starting value instead of 0.
