Example

The following example shows the usage of math.BigDecimal.precision() method.

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

   public static void main(String[] args) {

      // create 2 BigDecimal Objects
      BigDecimal bg1, bg2;
   
      bg1 = new BigDecimal("123.234");
      bg2 = new BigDecimal("523");

      // create 2 int objects
      int i1, i2;

      // assign the result of precision of bg1, bg2 to i1 and i2
      i1 = bg1.precision();
      i2 = bg2.precision();

      String str1 = "The precision of " + bg1 + " is " + i1;
      String str2 = "The precision of " + bg2 + " is " + i2;

      // print the values of i1, i2
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Let us compile and run the above program, this will produce the following result −

The precision of 123.234 is 6
The precision of 523 is 3
