Subject cvs commit: xml-axis/java/test/types TestUnsignedLong.java
Date Tue, 24 Sep 2002 21:06:09 GMT
tomj        2002/09/24 14:06:09

  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.
