Rounding off

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc. Rounding off numbers is done to preserve the significant figures. The number of significant figures in a result is simply the number of figures that are known with some degree of reliability.

Rounding Rules for Decimal Numbers

Rounding rules for decimal numbers are as follows:

Determine the rounding digit and look at its righthand side.
If the digits at the righthand side are less than 5, consider them as equal to zero.
If the digits at the righthand side are greater than or equal to 5, then add +1 to that digit and consider all other digits as zero.
