Question

Our application can get following numbers:

0.1
0.02
0.003

etc.

These values treated by our code as BigDecimal,as far we operate with money.

There is form on web UI, where user should view these floating parts of prices, transformed to following ones:

1
02
003

The question is,how to trim leading zero and delimiter character in input prices. Perhaps BigDecimal class has standard method something like trimLeadingZeroes(),but can’t find any.

UPDATE:
trim just leading zero and delimiter symbol

For instance:

1 is 0.1

27 is 0.27

Answer 1

Something like this?

public String getDecimalFractions(BigDecimal value) {
    String strValue = value.toPlainString();
    int index = strValue.indexOf(".");
    if(index != -1) {
        return strValue.substring(index+1, strValue.length());
    } 
    return "0"; 
}
