What does rounding off mean in a number system?
Rounding Numbers are used to ease the calculation by adjusting the digits.
Answer: In the number system, rounding off means the process of making a number simpler such that its value remains close to what it was.
To round off a number, there are a certain set of rules that need to be followed.
There are several instances in real life where we need to make assumptions on numbers. For example, making rough price estimates, percentage calculations, etc.
For example, we have a number 439, but for rough estimates, we may round it off as 440 to nearest ten and 400 to the nearest hundred as per our convenience.
Thus, Rounding off means modifying the numbers to make them simpler for calculation.
