MathContext getPrecision() Method in Java

The java.math.MathContext.getPrecision() is an in-built function in Java which returns the precision settings of the MathContext object. This value is always non-negative.

Syntax :

public int getPrecision()

Parameters: The method does not take any parameters.

Return Value: This method returns an int which is the value of the precision setting of the MathContext object.

Examples:

Input : m1 = new MathContext(7); 
Output : 7

Input : m1 = new MathContext(2, RoundingMode.HALF_UP);
Output : 2

Below programs illustrate the use of getPrecision() function :
Program 1 :

// Java program to demonstrate getPrecision() method
import java.math.*;
import java.io.*;

class GFG {
    public static void main(String[] args)
    {

        // Creating a MathContext object m1
        MathContext m1;

        // Assign context settings to m1
        m1 = new MathContext(2, RoundingMode.HALF_UP);

        // Displaying the result
        System.out.println(m1.getPrecision());
    }
}

Output:

2

Program 2 :

// Java program to demonstrate getPrecision() method
import java.math.*;
import java.io.*;

class GFG {
    public static void main(String[] args)
    {

        // Creating a MathContext object
        MathContext m1;

        // Assign context settings to m1
        m1 = new MathContext(50);

        // Displaying the result
        System.out.println(m1.getPrecision());
    }
}

Output:

50
