Tutorial :What is double(C++) in C#?



Question:

What is the double type(C++) in C#?

double experience;  

At first,I thought its UInt32,but its not. How to declare it in C#?


Solution:1

This is a question that is dependent upon the particular C++ compiler implementation you are using. The double type can be either 4 or 8 bytes according to the C++ standard. Most compilers do use 8 bytes though. Here are the closest representations

  • 4 bytes: float
  • 8 bytes: double

Solution:2

It is just double or Double. More specific double is a C# specific alias for System.Double.


Solution:3

Double in C# is Double.

double var1 = 0.123;


Solution:4

Not sure what the question is. A double in C# is the same as a double in C++. double is not an integral number in any mainstream language that I'm aware of.


Solution:5

I don't remember much about C++, but there is a double type in C#.

If you just want larger whole numbers, though, look at long.


Solution:6

C# has the double type as well.

double experience;  

should compile and work just fine in C#.
