> Maybe that's overkill, but it took me a while to find an input that
actually reached the `x.is_trivial_zero()` branch.
It's not overkill at all, after adding _a_ doctest to every function,
perhaps we will measure the coverage in terms of percentage of lines
executed with those tests. Thanks for spending the time and giving this
function 100% coverage. :)
BTW, `erf(SR(0))` should be a simple way of hitting the
`is_trivially_zero()` branch.
