In this example, bigdecimal class bigdecimal method working is demonstrated. Method return type is a bigdecimal value therefore it generates only bigdecimal object values.

Java bigdecimal scaleByPowerOfTen example

     

In this example, bigdecimal class bigdecimal method working is demonstrated. Method return type is a bigdecimal value therefore it generates only bigdecimal object values. The returned bigdecimal object value contains the product of its original value and product with  ten to the power n. In short the returned value is equivalent to this * (Ten to the power n). Where n is the integer variable passed inside the method parentheses. 

While running the programs, answer will come in scientific forms. Then here is the explanation.
for examle 6E + 2 means 6 * Ten to the power + 2
-45E - 6 means -45 * Ten to the power minus 6

Method throws NumberFormatException if it finds value other than integer and double. Method also throws ArithmeticException if scale crosses a 32-bit integer range. 

Syntax for using the method : public BigDecimal scaleByPowerOfTen(int n)

BigDecimal objects with names x & y;

System.out.print(x.scaleByPowerOfTen(n));
or
y = x.scaleByPowerOfTen(n);
