%description
Decimal rounding is non-trivial in binary arithmetic.  ISO standard round
to even is more rare than typically assumed as most decimal fractions are
not exactly representable in binary.  Our 'roundX()' versions explore
differences between current and potential future versions of round() in R.
Further, provides (some partly related) C99 math lib functions not in base
R.
