C# Math - PI Field
The C# PI field is used to return the value of 𝜋 to the available precision. It returns the value of 𝜋 as 3.1415926535897931.
Syntax
public const double PI = 3.1415926535897931;
Parameters
No parameter is required.
Return Value
Returns the value of 𝜋 to the available precision.
Example:
In the example below, Math.PI constant is used to return the value of 𝜋 to the available precision.
using System;
class MyProgram {
static void Main(string[] args) {
double pi = Math.PI;
Console.WriteLine("Math.PI = " + pi);
Console.WriteLine(
"Area of the circle with radius 1.0 is: " + pi*1*1);
}
}
The output of the above code will be:
Math.PI = 3.14159265358979 Area of the circle with radius 1.0 is: 3.14159265358979
