Java BigDecimal: Rounding to 2 Decimal Places with HALF_UP Mode

This line of code sets the scale of a BigDecimal value to 2 decimal places and rounds the value using the rounding mode of 'HALF_UP'. The resulting value is then converted to a double.

For example, if the original BigDecimal value was 3.45678, the code would round it to 3.46 and convert it to a double data type.
