---

---

Description

The java.math.BigDecimal.valueOf(long unscaledVal, int scale) translates a long unscaled value and an int scale into a BigDecimal. This "static factory method" is provided in preference to a (long, int) constructor because it allows for reuse of frequently used BigDecimal values.

Declaration

Following is the declaration for java.math.BigDecimal.valueOf() method.

public static BigDecimal valueOf(long unscaledVal, int scale)

Parameters

• unscaledVal − Unscaled value of the BigDecimal.

• scale − Scale of the BigDecimal.

Return Value

This method returns a BigDecimal whose value is (unscaledVal × 10^-scale).

Exception

NA

Example

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

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

   public static void main(String[] args) {

      // create a BigDecimal object
      BigDecimal bg;

      // create a Long Object
      Long l = new Long("12345678");

      // assign the bigdecimal value of l to bg
      // scale is 4
      bg = BigDecimal.valueOf(l, 4);

      String str = "The Value of BigDecimal using scale 4 is " + bg;

      // print bg value
      System.out.println( str );
   }
}

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

The Value of BigDecimal using scale 4 is 1234.5678
