How to set specific precision to BigDecimal in Java?

I have BigDecimal value.

BigDecimal price = new BigDecimal("100500100500.9999999").setScale(2, BigDecimal.ROUND_HALF_EVEN);

It prints 100500100501.00, although I need 100500100500.99. Is it possible to make some restriction to precision evaluating?

You can use the rounding mode constant ROUND_DOWN in setScale. However, the overloaded setScale method that takes a RoudingMode is preferred.

BigDecimal price = new BigDecimal("100500100500.9999999")
    .setScale(2, RoundingMode.DOWN);

Output:

100500100500.99
