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;
int i = x.scale();
