Countif only no-whole numbers

I have a database with numbered categorized products like so.

1.00 Food

1.01 Rice

1.02 Meat

1.03 Potato

2.00 Clothes

2.01 Pants

2.02 Shirts

I need to check how many products there are, meaning that the category headers (the ones with whole numbers) should not be counted. In the example the correct output would be "5".

I tried to use a countif + if function but i ended up having to use another column to make it work and that will create bugs in the future, any ideas on how to tackle this?

Edit: spelling
