Issues with comma separator in PBI Service

Hi.

I'm working with PBI Service and when I upload local CSV file, the only separator I have is comma and I can not change it.

So I have a question (because I faced with a problem): how can I upload a decimal number? For example, I want to upload this number: 0,5.

When I write like this: 0,5 - PBI Service thinks that comma here is separator.

When I write like this: 0.5 - PBI Service thinks that it's not a number but text.

Please, help me figure out with it.
