Define roundoff error
WebThis results in a standard deviation due to rounding of 0.5 / 4 = 0.125 lb. Since the measurement variation and rounding variation are almost equal, rounding is the largest source of measurement variation. Reporting the values to the nearest 0.1 lb. should reduce the measurement variation. WebNov 27, 2024 · $\begingroup$ Are you sure about the $0.1670840000$? Most programming languages will print a lot fewer digits of precision than they actually computed, so if you're only seeing $0.167084$ it does not necessarily mean that the next four digits are zero.
