Excellent question and a more than excellent explanation of why the correct answer is what it is.

Thanks -

If everything seems to be going well, you have obviously overlooked something.

Excellent question and a more than excellent explanation of why the correct answer is what it is.


Thanks - high praise indeed! I must mention though, that when trying to decide how to format the explanation, I came across this excellent post from SQL Kiwi (Paul White?) - which helped me considerably to come up with a clearer and more concise one than I would have done otherwise.

Cool

I am sorry, but I realy, realy don't understand why D is not good, even if I do your formula.

Why is so that D would have a truncate answer and not C?
I mean, both have a precision of 51 and only the scale is different (3 more digit more for C), which might explain something if you could explain my question here:

If I declare D as precision of 23 instead of 25 and still having a scale of 10
DECLARE @value1D DECIMAL(23,10), @value2D DECIMAL(23,10)
it is still a precision over 38, and the scale is still 20 as previous, but the answer is not truncate
Why??? Crazy

Thanks for the question, it really does show why we need to pay close attention to the data types we use.

Excellent question, with an excellent (If I may dare say, better than BOL) explanation!

Have a wonderful day!

Good question - an area often overlooked by developers.
