BigDecimal isn't only best choice, BigDecimal is designed for such case.

For most applications, a simple long will do: when representing cents, this will handle amounts up to 10^17 {Dollars, Euros, whatever}.

You almost certainly don't want to use floating-point types (double, float, Double, Float) to handle monetary amounts, especially if you will be performing computations on them. The main reason for this is that there are many simple-looking numbers that cannot be represented exactly as a double et al. One such number is 0.1.

BigDecimal is therefore a much better choice for this use case.

Use BigDecimal, it's a lot better than Double for financial stuff. See here the accepted answer for a similar question: Double vs. BigDecimal?
