- 0 is in the ones place and 6 is in the tenths place
- Since the digit in the tenths place (6) is greater than or equal to 5, add 1 to the digit in the ones place (0)
- 1 + 0 = 1, so the digit in the ones place becomes 1
- The decimal point and the digits to the right of the ones place are dropped
