You need to work on longdouble support I guess
I wrote the tests in question. I included object properties of type
DATE and NUMERIC to provide tests against regression of some changes
I had made to get_attr_val to fix type mismatches.
I realise that I made a mistake by using literal Perl floating point
numbers in the insert statements. Doing it this way means that, on
the route into Oracle, the number is converted first into Perl's binary
floating point format and then into Oracle's base-100 format.
(I was only interested in testing the route out of Oracle.)
I think the best fix is simply to use strings in the insert statements.
Change 12345.6789 to '12345.6789' and 777.666 to '777.666'. This
way, the conversions both ways will be done by Oracle. Conversion of
a decimal string representation to a base-100 representation of adequate
precision will be exact. Nothing will be hidden under the carpet.
I should have written it like this originally. I am sorry.
Here's a patch to make the test PASS on all systems, but I'm not sure
if I'm using a carpet to shuv the problems under ...
