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
