Question

When I run the query:

select (100/50)

It give me 2 – good.

But when I run the query:

select (50/100)

I was expected it will give me 0.5… but it gives me 0 instead? Why? and How can I get the 0.5?

select (25/(30))*100

I was expected it will give me 83.33 but it also gives 0 instead?

Answer 1

When you divide two integers, the result is an integer as well, so 50 / 100 is 0.5, which is an integer of 0.

To get a decimal point, either write:

Select 50.0 / 100

or Cast the integer o a decimal – i.e.

SELECT (CAST(20 AS DECIMAL(5,1))/30)
