- epistasis 2y ago> These calculations involve some elementary but easy to mess up algebra and some very demanding numerical calculations for which regular IEEE double precision is insufficient. If you'd like to double-check these results, be sure to use a multiple precision calculator with at least 30 significant digits of accuracy. So you're saying my iPhone built-in calculator app is going to have problems....? Time to whip out dc on the terminal.
