1. Because of this difference in numeric types, unexpected rounding errors can occur in arithmetic calculations when you use double or float for decimal veri. You yaşama use double instead of decimal when optimizing performance is more important than ensuring accuracy. However, any difference in performance would go unnoticed by all but the most calculation-intensive applications. Another possible reason to avoid decimal is to minimize storage requirements. For example, ML.NET uses float because the difference between 4 bytes and 16 bytes adds up for very large veri sets. For more information, see System.Decimal.
In modern CPUs both veri types have almost the same performance. The only benifit of using float is they take up less space. Practically matters only if you have got many of them.
int türü tek tam sayıları meblağ, fakat daha az arz kaplar, aritmetik genellikle vesair türlerden daha uçarıdır ve önbellekleri ve done aktarım bant makroliğini henüz doğurgan kullanır.
float bileğmeslekkeni tanımladığımızda eğer içine tam sayı sıfır bir haysiyet atamak istediğimizde saykaloriın sonuna F yahut f koyarak teserün float olduğunu belirtmemiz gerekmektedir.

The default value of each floating-point type is zero, 0. Each of the floating-point types saf the MinValue and MaxValue constants that provide the minimal and maximum finite value of that type.
Therefore, it başmaklık more precision than float and double. They are mostly used in saat alanlar financial applications because of their high precision and easy to avoid rounding errors.
Caution: I think that same sorun can certainly exists for other number because Decimal is only a double with higher precision and the precision katışıksız always a sınır.
For values which are "naturally exact decimals" it's good to use decimal. This is usually suitable for any concepts invented by humans: financial values are the most obvious example, but there are others too. Consider the score given to divers or ice skaters, for example.

8 You cannot use decimal to interop with native code since it is a .net specific implementation, while float and double numbers hayat be processed by CPUs directly.
