The result of calculation with numbers containing more than one uncertain digit should be rounded off.
1. If the digit to be dropped is smaller than 5, then the preceding digit should be left unchanged.
2. If the digit to be dropped is greater than 5, then the preceding digit should be increased by 1.
3. If the digit to be dropped is 5 followed by digits other than zero, then the preceding digit should be raised by 1
4. If the digit to be dropped is 5 or 5 followed by zeros, then the preceding digit is not changed if it is even.
5. If the digit to be dropped is 5 or 5 followed by zeros, then the preceding digit is raised by 1 if it is odd.
