MathContext Class getPrecision() method

• getPrecision() method is available in java.math package.
• getPrecision() method is used to get the precision settings of this MathContext object when it exists.
• getPrecision() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• getPrecision() method does not throw an exception at the time of returning precision.

Syntax:

    public int getPrecision();

Parameter(s):

• None

Return value:

The return type of this method is int, it returns the precision value of this MathContext object.

Example:

// Java program to demonstrate the example 
// of int getPrecision() method of MathContext

import java.math.*;

public class GetPrecisionOfMC {
    public static void main(String args[]) {
        // Initialize three MathContext objects  
        MathContext ma_co1 = new MathContext(3, RoundingMode.HALF_UP);
        MathContext ma_co2 = new MathContext(4);
        MathContext ma_co3 = new MathContext(6, RoundingMode.FLOOR);

        // returns the precision of this MathContext
        // ma_co1 i.e. precision is the first
        // parameter set in MathContext Constructor
        // i.e. 3 in ma_co1
        int precision = ma_co1.getPrecision();
        System.out.println("ma_co1.getPrecision(): " + precision);

        // returns the precision of this MathContext
        // ma_co2 i.e. precision is the first
        // parameter set in MathContext Constructor
        // i.e. 4 in ma_co2
        precision = ma_co2.getPrecision();
        System.out.println("ma_co2.getPrecision(): " + precision);

        // returns the precision of this MathContext
        // ma_co3 i.e. precision is the first
        // parameter set in MathContext Constructor
        // i.e. 6 in ma_co3
        precision = ma_co3.getPrecision();
        System.out.println("ma_co3.getPrecision(): " + precision);
    }
}

Output

ma_co1.getPrecision(): 3
ma_co2.getPrecision(): 4
ma_co3.getPrecision(): 6
