sum types in csharp

To sum variables of different types in C#, you need to perform type conversion to have all variables of the same type. You can do this by using explicit conversion or by using implicit conversion.

Explicit conversion involves casting the variables to a common type, while implicit conversion is automatically performed by the compiler.

Here is an example that shows how to sum variables of different types using explicit conversion:

main.cs
int a = 10;
double b = 20.5;
decimal c = 30.7m;
float d = 5.5f;

// Convert all variables to decimal
decimal total = (decimal)a + (decimal)b + c + (decimal)d;

Console.WriteLine(total); // Output: 66.7
202 chars
10 lines

In this example, we convert all variables to decimal using explicit casting, which allows us to perform addition between them.

Keep in mind that when summing values of different types, you need to take care of the overflow and precision issues that may arise.
