I hope your big matrix has many elements much larger than 4.7e-06,
so that you don't really have to worry about which package has the
smaller roundoff error. If you *are* in the situation of having to
worry about roundoff error, that's likely to mean that you have to
plan your entire computation around the goal of minimizing its
susceptibility to tiny amounts of noise, and that's a problem much
more complex than choosing a language.
