No, you can't use var while defining the constant. You should use any of other data-type while defining constant. Otherwise, you can use var too.

const (C# Reference) https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/const

While we define constant, it is not required to be double. You can surely change data-type of constat variable. I made a simple example where I defined constat with 4 different data-types. https://code.sololearn.com/c7CUxrGvYkf6/?ref=app

you want to declare a constant variable so use const keyword instead of var keyword

because the value assigned to constant cannot be changed,
