Retaining floating point values

Question

I have a calculation to be done in a query: ((28154/3745181) * 100), whose resultant value is .751739 which I want as 0.75.

But when I try to do it in a query, I get 0 as shown below:

select ((28154/3745181) * 100) --Returns 0 as the result.

How can I get the desired 0.75 as the resultant?

Answer 1

You are doing integer arithmetic because your types are integer types.

select ((cast(28154 as float)/cast(3745181 as float)) * 100)

However you are obviously trying to get percentages so this is an alternative:

select((100 * 28154) / 3745181 )

I.e. do the multiplication first, then the division.
