Program in java to print the pie value(pi)

Program in java to print the pie value(pi). The lowercase Greek letter sometimes spelled pi, is used by mathematicians to denote the ratio of a circle’s circumference to its diameter.

It is derived from the initial letter of the Greek word perimeters, which means circumference. is pronounced “pie” in English.  We can utilize the Math.PI constant defined in the java.lang.Math class to get and use the PI () value in Java. 

The Math.PI variable is a static final double type variable with a double value that is the closest to the ratio of a circle’s circumference to its diameter.

PI = 3.14 is the value of pie in java. Because it is a static variable, we can access it directly using its class name, such as Math.PI.

class Main 
{
public static void main(String[] args)
{
double x = Math.PI;
System.out.println(x);
}
}

Output:

3.14159265358979323846

What is pie value and the shocking facts behind the pi value in java

A mathematical constant is a number. It is defined as the circumference to diameter ratio of a circle, with several similar definitions.

Since the mid-eighteenth century, it has been symbolized by the Greek letter “,” which is spelled out as “pi.”

It’s also known as Archimedes’ constant, and it’s pronounced ‘pie.’ It’s one of the most often used constants in mathematics.

It’s the diameter of a circle divided by its circumference. In some aspects, Pi () is a very simple number to calculate; all you have to do is take any circle and divide its circumference by its diameter to get Pi.

Haruka Iwao established a world record by utilizing Google cloud technology to calculate Pi to 31.4 trillion digits. Here’s the entire mind-boggling figure: There are 31,415,926,535,897 digits in this number.

What is Math.pi in java and how to declare in java program

In the Java.lang. math class, the PI constant is defined. The Calculation. PI is a static final double type variable with a double value that is closest to the ratio of a circle’s circumference to its diameter than any other.

The constant keyword can be used to declare constant variables. Macro can be used to specify constants, such as double pi = 3.14 or constant variables. In Java, there are a lot of predefined constants.
