* Floating-point Equality in Two Tests
Merging a change today, Git reported failures that did not occur during "normal" unit testing. The merge still succeeded, but ... The problem was an error comparing float values for equal, and the inequality occurred beyond the 14th decimal digit. Change the tests in question, which incidentally were not part of the merged changed, to use assertEqualsWithDelta.
* Egad - 112 More Precision-related Problems
Spread across 9 test members.
- Move TREND() functions into the Statistical Trends class
- Unit tests for TREND()
- Create Confidence class for Statistical Confidence functions, and the CONFIDENCE() method
* Stacked Alignment - Use Class Constant Rather than Literal
PR #1580 defined constants for "stacked" alignment in cells.
Using those constants outside of Style/Alignment was beyond the
scope of the original PR, but I said I would get to it.
This PR replaces all uses of literal -165, and appropriate uses of
literal 255, with the named constants, and adds tests to make sure
that the changed code is covered in the test suite.
Because even if it doesn't make a difference in practice, it is
technically more correct to call static methods statically. It
also better advertise that those methods can be used from any context.
