Java, extract just the fractional part of a BigDecimal?

Question

In Java, I'm working with the `BigDecimal` class and part of my code requires me to extract the fractional part from it. `BigDecimal` does not appear to have any built in methods to help me get the number after the decimal point of a `BigDecimal`. For example: ``` BigDecimal bd = new BigDecimal("23452.4523434"); ``` I want to extract the `4523434` from the number represented above. What's the best way to do it?

Accepted Answer

I would try `bd.remainder(BigDecimal.ONE)`.

Uses the `remainder` method and the `ONE` constant.

```
BigDecimal bd = new BigDecimal( "23452.4523434" );
BigDecimal fractionalPart = bd.remainder( BigDecimal.ONE ); // Result:  0.4523434
```
