<H3>Disadvantage of decimal representation</H3>
-Advantages stated so far can also be disadvantages if the input from outside is
- represented in binary.
-Translation error from decimal to binary or vice versa is inevitable.
-So,translation from Float(binary) to BigDecimal(decimal) is not alway done exactly.
+Because most computers have no internal decimal representaion.
+Once you use BigDecimal,you need to keep using it without
+considering computation cost if exact computation is required.
<H4>Which is the first input?</H4>
Because most people uses decimal notatin for numeric data representation,
