Morten is right that some values input for inverses tests are not fair
to any spreadsheet processor. I hope to find ways to provide more
informative output, that is, how the calculation fares in relation to
what is reasonable at the default precision. The current example is VERY
preliminary, and I simply copied values from one test to another.
Some of the more interesting tests are the bounds ones. These allow
comparison with simple functions that can be locally computed. There are
other examples of such functions, and a compromise is needed between
different objectives to get a "nice" test.
For the moment I am avoiding the r.foo functions. Later on I hope to add
to the Gnumeric-specific test files. For the moment I'm concentrating on
ones that can be saved as .xls. I find these useful to send to Excel
addicts.
