C# double (Floating-point)

The double data type is used to store floating-point numbers (numbers with decimals). It provides double the precision of the float data type, making it suitable for calculations requiring a higher degree of accuracy.

Key Concepts

  • The double type is a 64-bit floating-point number.
  • It is typically used for scientific calculations, real-time data processing, or any calculations involving decimals.
  • When precision is less critical, consider using the float type.

Example of Using a double

Code Example

// Declare a double variable
double myDouble = 9.99;

// Output the double to the console
Console.WriteLine(myDouble);

Output:

9.99

Code Explanation: The double variable myDouble is initialized with the value 9.99. It is printed using the Console.WriteLine() method.

Output Explanation: The value 9.99 is displayed on the console, which is the value assigned to myDouble.
