Analytics.Transaction: converting price to decimal

The price amount for iOS and Android in-apps are strings, and to send it to Analytics.Transaction() we have to convert it to decimal.
However, For iOS this is simple:
decimal price = decimal.Parse(product.price);
because price contains numeric value. But for Android this is not so easy, because price is formatted like $0.99 or 14.28₴, etc.
Are someone found a solution to get/parse Android decimal price at Unity side?

Thanks.
