Question
Why there is a need of rounding off figures during calculation?
Advertisements
Solution
- When performing calculations with measured quantities, the rule is that the accuracy of the final result is limited to the accuracy of the least accurate measurement.
- In other words, the final result cannot be more accurate than the least accurate number involved in the calculation.
- Sometimes, the final result of a calculation often contains figures that are not significant.
- When this occurs, the final result is rounded off.
