Hi, Have you checked mathematics operation (add, subtract, multiply, divide etc) with data type bigdecimal in doc:http://docs.oracle.com/javase/6/docs/api/java/math/BigDecimal.html? You can use setScale() function for bigdecimal which will help u for rounding or setting the scale. Elaborating your case with an example with input and expected output values will be preferred.
