Question

What does rounding off mean in a number system?

Answer 1

Define rounding off in a number system.

An approximate value is a value that is closest to the actual value known as rounding off.

Example: Rounded to the closest hundredth.

$$\begin{gathered} 35.2678\approx 35.27 \\ 48.3476\approx 48.35 \\ 56.0781\approx 56.08 \\ 86.1666\approx 86.17 \end{gathered}$$

Hence, the rounding off in a number system means the approximate values which are close to the actual value.
