BigDecimal unscaledValue() in Java
  • Last Updated : 04 Dec, 2018

The java.math.BigDecimal.unscaledValue() is an inbuilt method in java that returns a BigInteger whose value is the unscaled value of a BigDecimal value. The value computes (this * 10this.scale()).

Syntax:

public BigInteger unscaledValue()

Parameters: The method does not accepts any parameter.

Return value: This method returns a BigInteger whose value is the unscaled value of this BigDecimal value.

Below program illustrates the BigDecimal.unscaledValue() method:
Program 1:






// Program to illustrate unscaledValue() method of BigDecimal 
  
import java.math.*;
  
public class Gfg {
  
    public static void main(String[] args)
    {
  
        // Creating 2 BigInteger objects
        BigInteger i1, i2;
  
        BigDecimal b1 = new BigDecimal("175.856");
        BigDecimal b2 = new BigDecimal("-275.73");
  
        // Assigning unscaledValue of BigDecimal objects b1, b2 to i1, i2
        i1 = b1.unscaledValue();
        i2 = b2.unscaledValue();
  
        // Printing i1, i2 values
        System.out.println("The Unscaled Value of " + b1 + " is " + i1);
        System.out.println("The Unscaled Value of " + b2 + " is " + i2);
    }
}
Output:
The Unscaled Value of 175.856 is 175856
The Unscaled Value of -275.73 is -27573

Program 2:




// Program to illustrate unscaledValue() method of BigDecimal 
  
import java.math.*;
  
public class Gfg {
  
    public static void main(String[] args)
    {
  
        // Creating 2 BigInteger objects
        BigInteger i1, i2;
  
        BigDecimal b1 = new BigDecimal("5.5");
        BigDecimal b2 = new BigDecimal("-2.73");
  
        // Assigning unscaledValue of BigDecimal objects b1, b2 to i1, i2
        i1 = b1.unscaledValue();
        i2 = b2.unscaledValue();
  
        // Printing i1, i2 values
        System.out.println("The Unscaled Value of " + b1 + " is " + i1);
        System.out.println("The Unscaled Value of " + b2 + " is " + i2);
    }
}
Output:
The Unscaled Value of 5.5 is 55
The Unscaled Value of -2.73 is -273
