title: Set all BigDecimal operations to a certain precision?
body: <p>My Java program is centered around high precision calculations, which need to be accurate to at least 120 decimal places.<br>
  Consequentially, all non-integer numbers will be represented by BigDecimals in the program.</p>
  
  <p>Obviously I need to specify the accuracy of the rounding for the BigDecimals, to avoid infinite decimal expressions etc.<br>
  Currently, I find it a massive nuisance to have to specify the accuracy at every instantiation or mathematical operation of a BigDecimal.</p>
  
  <p>Is there a way to set a 'global accuracy' for all BigDecimal calculations?<br>
  (Such as the <code>Context.prec()</code> for the <em>Decimal</em> module in python)</p>
  
  <p>Thanks</p>
