Question

Here is the query i am running

Select (100/18)*18

The answer i get is 90. I have tried declaring each of the numbers as decimals also, and i get the value 100.0008, but when i calculate with variables as floats the answer is correct at ‘100’ so does anyone have any idea why SQL calculates like this?

Answer 1

Because it will first evelute the paranthesis

So

Select (100/18)*18

will (100/18) = 5.555555 but it assume both number as int so it will cast the result as int so it will return 5

so now 5*18 = 90

If you want the correct result do this instead Select (100*18)/18
