I wrote a simple code to calculate the area and I wanted it to take into account 4 decimal places after the comma. However, in one of the entries in my program, it disregards the 0 at the end of the number. I wanted to know what would be the correct way to make it consider the complete number with four decimal places.
Code:
var pi = 3.14159;
var raio = 150.00;
var area = pi * (raio * raio);
Console.WriteLine($"X = {Math.Round(area,4)}");
Output obtained: 70685,775
Expected Ouput: 70685,7750

var pi = 3.14159;
var raio = 150.00;
var area = pi * (raio * raio);
Console.WriteLine(String.Format("X = {0:F4}", area));
or
var pi = 3.14159;
var raio = 150.00;
var area = pi * (raio * raio);
Console.WriteLine($"X = {area.ToString("F4")}");
or
var pi = 3.14159;
var raio = 150.00;
var area = pi * (raio * raio);
Console.WriteLine($"X = {area:F4}");
