Please confirm: INT columns in calculations return INT results?

Question

Is it true that, when creating a formula-based column in Answers, dividing an INT typed logical column into an INT typed logical column will result in an INT typed result?
I must have missed something fundamental here, but it seems counter-intuitive that you can't divide two numbers--regardless of how they are defined--into each other and get a fractional result.
It only worked as expected when I changed the physical column datatype of one of the logical columns to DOUBLE. Likewise, I suppose I could unmap the logical columns and cast them as DOUBLEs.
Apparently, I missed something fundamental here. Clarification would be most welcome.

The OP doesn't expect those columns to be logged though.  He's performing an update on a table with a unique key, so GoldenGate should be extracting a fieldcomp (compressed update) record type with just the unique key values plus the column he's updating.
In my example above, I ran a straight forward "add trandata test.rowid_test" command and confirmed that GoldenGate had correctly created a supplemental log group containing my two unique key columns.
Also I reviewed the extract log and GoldenGate is already identifying the correct key values -
Wildcard TABLE resolved (entry TEST.*):
  TABLE "TEST"."ROWID_TEST";
Using the following key columns for source table TEST.ROWID_TEST: COL1, COL2.
I did actually try the KEYCOLS clause of my TABLE extract parameter at the time, as a possible workaround.  Unfortunately it made no difference.
I also reviewed the redo content with log miner and every column is logged into the redo, so GoldenGate is just acting on what it finds.  That's why I think really this one is going to be a case of raising a bug report with Oracle Support which will probably end up with the core database team.
My testing was on 11.2.0.4 by the way.
