Question

1. Why there is a need of rounding off
figures during calculation ?​

Answer 1

Rounding off of figures during calculation helps to make calculation of big digits easier.

It will be difficult to multiply a decimal number and will take a lot of time so for making it easier we round it off . If the first digit after decimal is greater than equal to 5 then we shall add 1 with the last digit before the decimal.

For example if the number is 467.62 then the round off number will be 468.
