Today, the data collected in the database is a bit large, and one output is automatically converted into scientific notation. It was later discovered 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 ("Scientific count:" + db.tostring ());

System.out.println ("Normal count:" + db.toplainstring ());

Output:

Scientific Count: 1.123456789E7

Normal Count: 11234567.89
