title: Set specific precision of a BigDecimal
body: <p>I have an <a href="https://en.wikipedia.org/wiki/XSD">XSD</a> that requires me to use a BigDecimal for a lat/lon.  I currently have the lat/lon as doubles, and convert them to BigDecimal, but I am only required to use about 12 places of precision.  I have not been able to figure out how to set that.  Can anyone help me with this?</p>
