the decimal module in python provides option rounding decimal : round_05up what practical uses type of rounding? the ieee decimal arithmetic spec has it: the rounding mode round-05up permits arithmetic @ shorter lengths emulated in fixed-precision environment without double rounding. example, multiplication @ precision of 9 can effected carrying out multiplication @ (say) 16 digits using round-05up , rounding required length using desired rounding algorithm. in other words, if round 1 precision using round_05up , round shorter precision using other rounding mode, result same if had directly rounded shorter precision.
