You can use setScale to round number to any given decimal places.
BigDecimal number = new BigDecimal(2.36359);
float rounded = number.setScale(2, RoundingMode.DOWN).floatValue();
System.out.println(rounded); // prints "2.36"
Once you have the BigDecimal. Use x.floatValue() to compute float and then pass it through Math.round() to round it to 2 digits.
