This should be zero.
Why `should' it? The documentation says:
'zapsmall' determines a 'digits' argument 'dr' for calling
'round(x, digits = dr)' such that values "close to zero" (compared
with the maximal absolute one) are "zapped", i.e., treated as '0'.That value is not small compared with the maximal absolute one: it is equal to it.
