Java Math - PI Field
The Java PI field is used to return the value of 𝜋 to the available precision. It returns the value of 𝜋 as 3.141592653589793.
Syntax
public const double PI = 3.141592653589793;
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.
public class MyClass {
public static void main(String[] args) {
double const_pi = Math.PI;
System.out.println("Math.PI = " + const_pi);
System.out.println(
"Area of the circle with radius 1.0 is: " + const_pi*1*1);
}
}
The output of the above code will be:
Math.PI = 3.141592653589793 Area of the circle with radius 1.0 is: 3.141592653589793
