Are you sure?
When I try

decimal d1 = 4.61m;
decimal d2 = 4.61m;
decimal d = d1 + d2;

it works as expected.
Of course if you were to try and add int and decimal it would but decimal and decimal?

If you want to sum 2 decimals you should use the static method "Add" which will undestand that you are dealing with decimal types.

System.Decimal d =  System.Decimal.Add(4.61m, 4.61m);
result is 9.22

Actually I have two quantities (4.61) stored as decimal numbers. Why
if I try to sum them the result is 9.23 if the correct value is 9.22?

Thank you
