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() methodimport 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() methodimport 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
