What is mean by rounding off?
Rounding off:
Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use.
To round off decimals:
- Find the place value you want (the "rounding digit") and look at the digit just to the right of it.
- If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.
- If that digit is greater than or equal to 5, add 1 to the rounding digit and drop all digits to the right of it.
To round off whole numbers:
- Find the place value you want (the "rounding digit") and look to the digit just to the right of it.
- If that digit is less than 5, do not change the "rounding digit" but change all digits to the right of the "rounding digit" to zero.
- If that digit is greater than or equal to 5, add 1 to the rounding digit and change all digits to the right of the rounding digit to zero.
