Round Numbers Rules

Sometimes, measurements in physics result non-integer numbers. Hence, it is more practice and easier the counting process if the numbers resulting from the measurements is rounded. The rules of the rounding are as follows :

1) The number that is bigger than 5 is rounded up.

For example : 

• 52.527 is rounded into 52.53

2) The number that is smaller than 5 is rounded down.

For example : 

• 24.674 is rounded into 24.67

3) The number of exact 5 is rounded up if the number before it is uneven number and it is rounded down if the number before it is even.

For example : 

• 24.235 is rounded into 24.24
• 24.225 is rounded into 24.22
