Question

Why there is a need of rounding off figures during calculation

Answer 1

it is necessary because of precision and perfection

Answer 2

Explanation:

It because if we do direct calculation such as

8.00362 X 5.01274

Its calculation will be complecated.

If we round off i.e.

8.00362 = 8

and 5.012374 = 5

Now, the calculation will be easy.

Thats why, we round off the figure during calculations.
