I have a BigDecimal field amount which represents money, and I need to print its value in the browser in a format like $123.00, $15.50, $0.33.
How can I do that?
(The only simple solution which I see myself is getting floatValue from BigDecimal and then using NumberFormat to make two-digit precision for the fraction part).

BigDecimal doesn't have a dot or a comma.
BigDecimal. round(MathContext mc) returns a BigDecimal rounded according to the MathContext settings. If the precision setting is 0 then no rounding takes place.
stripTrailingZeros() is an inbuilt method in Java that returns a BigDecimal which is numerically equal to this one but with any trailing zeros removed from the representation. So basically the function trims off the trailing zero from the BigDecimal value.
public static String currencyFormat(BigDecimal n) { return NumberFormat.getCurrencyInstance().format(n); } It will use your JVM’s current default Locale to choose your currency symbol. Or you can specify a Locale.
NumberFormat.getInstance(Locale.US) For more info, see NumberFormat class.
