Knut Anders Hatlen updated DERBY-5986:
--------------------------------------
Attachment: d5986-1a-decimal.diff
Attaching a patch that makes ArithmeticTest test the DECIMAL data type.
Most of the test cases worked on DECIMAL with no changes. What needed to be
changed was:
- Assumptions that the negative boundary for numeric data types was
-positiveBoundary-1. For DECIMAL, the range of legal values is symmetric around
zero.
- Canons that asserted results were always integers. With DECIMAL, the results
of divisions could have a fraction part.
- Needed to use BigDecimal to represent and test boundary values, as the
DECIMAL type supports values outside the Java long range.

> Project: Derby
> Issue Type: Improvement
> Components: Test
> Affects Versions: 10.10.0.0

> I noticed in the code coverage report that the DECIMAL data type has less
> test coverage than the other numeric data types. One way to improve it may be
> to make existing tests for other numeric types also test the DECIMAL type.
> ArithmeticTest is one such test.
