What will be an ideal response?
If the digit to the right of the one you are rounding to is 5 or larger add 1 to the digit you are rounding to. If the digit is 4 or smaller, do not change it. Drop all digits to the right of the digit you are rounding to. Replace each dropped digit to the left of the decimal point, if any, with 0. Another way is truncation. Drop all the digits to the right of a given decimal place.
