I am currently using double to sum up a bunch of big number with decimal places. I try to export some data in csv format, and one of the field belong to what I just said. However, i see 7.8923932482495E9(for example) in my csv file. I am wonder how can I get the number completely, e.g 78923932482495.79. My friend tell me to use BigDecimal class, however, I only see it has some functions to wrap up the long data type. "long" is not what I want since my field has decimal places.
Can anybody give me suggestions to solve this question?
