Answer 1

You can use Standard Numeric Format Strings (complex name for something rather simple!)

double a = 4.0;
double b = 4.0;

Console.WriteLine((a+b).ToString("N1"));

We're telling the compiler to first add a and b (8) and use the Numeric Formatting (N stands for Number and 1 for the amount of decimal places) to display: 8.0
