Round of Method

double x = Math.Round(1.5);

double z = Math.Round(2.5); 

Console.WriteLine(x);

Console.WriteLine(z);

if you run this code then you will see that the answer of x and z is 2 because "roundof()" methos always give us answer in even number.

double x = Math.Round(1.5);

double z = Math.Round(3.5);

Console.WriteLine(x);

Console.WriteLine(z);

if you run this code then you will see that the answer of x is 2 and answer of z is 4 because "roundof()" methos always give us answer in even number.

Thats why we prefer to use "Math.Floor()" and "Math.Ceiling()" function rather then "roundof()" method.
