Hi Pankaj,
You can use the following : 
Decimal num1 = 12.4;
System.debug(num1.round(System.RoundingMode.HALF_UP)) ; // Output :  12
Decimal num2 = 12.5;
System.debug(num2.round(System.RoundingMode.HALF_UP)) ; // Output :  13
Decimal num3 = 12.6;
System.debug(num3.round(System.RoundingMode.HALF_UP)) ; // Output :  13

I hope this solves your issue. If yes, please mark this as the best answer.

Regards
Deepak
