[java] Set specific precision of a BigDecimal

I have an XSD 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?

Try this code ...

    Integer perc = 5;
    BigDecimal spread = BigDecimal.ZERO; 
    BigDecimal perc = spread.setScale(perc,BigDecimal.ROUND_HALF_UP);
    System.out.println(perc);

Result: 0.00000

You can use setScale() e.g.

double d = ...
BigDecimal db = new BigDecimal(d).setScale(12, BigDecimal.ROUND_HALF_UP);

 BigDecimal decPrec = (BigDecimal)yo.get("Avg");
 decPrec = decPrec.setScale(5, RoundingMode.CEILING);
 String value= String.valueOf(decPrec);

This way you can set specific precision of a BigDecimal.

The value of decPrec was 1.5726903423607562595809913132345426 which is rounded off to 1.57267.
