Of course there is rounding, but no-one suggested it was visible in the formulae. Half an odd number cannot be represented as a whole number and the end result is necessarily rounded either up or down. This is true even if the calculation is done in floating point rather than rational arithmetic. As I said, much depends on whether the rounding occurs at the end (as I would expect, and as the OP's report suggests) or at each stage of the calculation (which is inconsistent with the OP's report). _______________________________________________ gnucash-user mailing list gnucash-user@gnucash.org To update your subscription preferences or to unsubscribe: https://lists.gnucash.org/mailman/listinfo/gnucash-user If you are using Nabble or Gmane, please see https://wiki.gnucash.org/wiki/Mailing_Lists for more information. ----- Please remember to CC this list on all your replies.
