Significant Figures
|
Working backwards from a rounded number to a range of values that it may have come from called finding the limits of accuracy. The upper and lower values as sometimes called 'boundary limits'.
To calculate the limits of accuracy for a number x, go 1/2 way up, and 1/2 way down to the closest numbers that have the same significant figure as x. |
