If the digit to be dropped is less than 5,then the preceding digit is left unchanged.
Ex: 7.82=7.8

Rule2:
If the digit to be dropped is more than 5 ,then the preceding digit is raised by one.
Ex:5.328=5.33

Rule3:
If the digit to be dropped is 5 followed by digits other than zero,then the preceding digit is increased by 1.
Ex:14.252=14.3

Rule4:
If the digit to be dropped is simply 5 or 5 followed by zeros,then the preceding digit is left unchanged if it is even.
Ex:6.250=6.2

Rule5:
If the digit to be dropped is 5 or 5 followed by zeros,then the preceding digit is raised by one,if it is odd.
