Contiguous digit sets and local roundings


We determine for which rouiidings adrlitioii in the floating-point screen has representable rounding error, whicli rouiiclings are implied by truncation of digit strings i n different radix systems with contiguous digits, and how rnany additional digits (including possibly a sticky bit) have to I)c kept in such systems in orcler to perforin a given… (More)
