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

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#?

From stackoverflow

• Double in C# is Double.

  double var1 = 0.123;

• C# has the double type as well.

  should compile and work just fine in C#.

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

• 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.

• 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.

• 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

  Richard Szalay : and 16 bytes: decimal Also of note, float and double are IEEE, decimal is not.

  MSalters : decimal floating point is IEEE nowadays. Thank IBM; they've managed to standardize their mainframe stuff.

  MSalters : THe C++ standard does not specify 4 or 8 bytes at all. It sets some requirements on minimum ranges and precision. But 7 bytes with 9 bits each would be OK.
