Modified: java/src/org/apache/axis/types UnsignedLong.java
java/test/types TestUnsignedLong.java
Log:
Fix bug 12969 - UnsignedLong doesn't format correctly
Remove code that was chopping off thenumber after the decimal for string
formatting as this is bad when the number is 1.234567E7.
Add a test case for the problem, and enhance test which exposed
more limits of precision.
