Today found that the data summarized in the database is a bit large, one output is automatically converted into scientific counting method. It was later found that there was a problem with the method of converting strings. As follows: String a = "11234567.89"; BigDecimal db = new BigDecimal (a); SYSTEM.OUT.PRINTLN ("Science counts:" + db.tostring ()); System.out.println ("Ordinary count:" + db.toplainstring ()); Output: Scientific Count: 1
