Java bigdecimal scale example

     

In this example, bigdecimal class scale method working is demonstrated. Method return type is int therefore it generates only integer value. 
Method only generates negative, positive and zero values. For zero and any positive bigdecimal  value , the method generated scale will be the number of digits towards the right of decimal point (dot operator). 

For any negative bigdecimal  object value the method generated scale will be the product of the scale of the object's unscaled value with power ten. 

For example a scale of -4 means the unscaled value is multiplied by 1000. This is demonstrated in the example. 
Method throws NumberFormatException if it finds value other than integer and double.

Syntax for using the method : public int scale()

BigDecimal objects with names x;
System.out.print(x.scale());
or
int i = x.scale();

Java_bigdecimal_scale.java

import java.math.BigDecimal;

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

  BigDecimal nc = new BigDecimal(0),
  mc = new BigDecimal(0.050);
  System.out.println("nc value : " + nc);
  System.out.println("method generated " +
  "result : " + nc.scale());

  System.out.println("mc value : " + mc);
  System.out.println("method generated " +
  "result : " + mc.scale());

  nc = new BigDecimal(-3.0);
  mc = new BigDecimal(-6);

  System.out.println("\nnc value : " + nc);
  System.out.println("method generated " +
  "result : " + nc.scale());

  System.out.println("mc value : " + mc);
  System.out.println("method generated " +
  "result : " + mc.scale());

  nc = new BigDecimal(-1);
  mc = new BigDecimal(-42);

  System.out.println("\nnc value : " + nc);
  System.out.println("method generated " +
  "result : " + nc.scale());

  System.out.println("mc value : " + mc);
  System.out.println("method generated " +
  "result : " + mc.scale());

  }
}
