Hmm, I think they'd qualify as terms of art; I don't know that rounding to
an arbitrary decimal place would be (although useful) primitive enough that
they should be added in stdlib [also, to genericize over floats and
doubles, how many decimal places could you usefully get?]; and grouping
families of methods by name has been rejected as a criterion for naming,
though obviously it's elegant where possible.
