How to get the list of digits in the scale representing the BigDecimal
<p>I have 3 BigDecimal  objects 9.1, 9.12, 9.123 and I am looking to get the number of digits in the scale which would be 1, 2 and 3 for the above decimals. How do I get this?</p>

<p>Should I get the scale and then do String.length or is there a simpler way?</p>
