Fix with rev 825680. Thanks Mark for the fix.
> xsd2inst incorrectly handling decimal precision
> -----------------------------------------------
>
> Key: XMLBEANS-410
> URL: https://issues.apache.org/jira/browse/XMLBEANS-410
> Project: XMLBeans
> Issue Type: Bug
> Components: Tools
> Affects Versions: Version 2.4.1
> Environment: All OS, all hardware
> Reporter: Mark D Henning
> Fix For: Version 2.4.1
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> as an example, a xs:decimal (totalDig:20, fracDig:0) was creating 1000.00
> whic of course, does not validate.
> The problem is in the org.apache.xmlbeans.impl.xsd2inst.SampleXmlUtil.java
> class.
> Root cause of the problem is that the programmer was calling the setScale()
> method on a BigDecimal, as though it modifies the existing BigDecimal object
> (i.e. BigDecimal bd = new BigDecimal("1000.00"); bd.setScale(1)) setScale
> does not modify the existing, but returns a new BigDecimal object. Therefore
> the correct call would be (BigDecimal bd = new BigDecimal("1000.00"); bd =
> bd.setScale(1)).
> The lines included below represent the repair of the formatDecimal() method
> which is the eronious function.
> // We have the number
> // Adjust the scale according to the totalDigits and fractionDigits
> int digits = 0;
> BigDecimal ONE = new BigDecimal(BigInteger.ONE);
> for (BigDecimal n = result; n.abs().compareTo(ONE) >= 0; digits++)
> n = n.movePointLeft(1);
> if (fractionDigits > 0)
> if (totalDigits >= 0)
> result = result.setScale(Math.max(fractionDigits, totalDigits
> - digits));
> else
> result = result.setScale(fractionDigits);
> else if (fractionDigits == 0)
> result = result.setScale(0);
> return result.toString();
> }
> I would recommend that the code tree be searched for other setScale method
> calls to see if others need to be fixed. I currently do not have write
> access to the subversion repository, so I am unable to check this fix in
> myself.
> I was unsure whether to code this as a minor or major problem. It appears
> that the difference between the two is the presence of a work-around, for
> which there is none in this case.
