Knowledge Box...!
- It is necessary to know that round() and rint() are not same.
- Math.round() returns number in int data type while Math.rint() returns number in double data type.
- Another Difference... Let's take -9.5 as a parameter Math.round(-9.5) will return -9 while Math.rint(-9.5) returns -10.0
