Follow-up Comment #28:

Ernst,
Yes I have Matlab (r2016b prerelease), at work I have several more versions,
the oldest (retired but still present) r2007a, then 2012a, 2014a and 2016b.

After a bit more delving into it w Matlab (r2016b) it shows that you are
right.

The reason I was a bit misled is that Matlab acts deceptively: in the command
terminal it does show the converted value (doubles) of java.math.BigDecimal
objects, i.e. suggesting autoconversion, but it does not really convert them
to doubles behind the scenes.
So in way it converts them but at the same time not.

To show what I mean:

>> cl = sh.getCellAt (0, 0)
cl =
<table:table-cell
xmlns:table="urn:oasis:names:tc:opendocument:xmlns:table:1.0"
xmlns:office="urn:oasis:names:tc:opendocument:xmlns:office:1.0"
office:value-type="float" office:value="1"
xmlns:calcext="urn:org:documentfoundation:names:experimental:calc:xmlns:calcext:1.0"
calcext:value-type="float"><text:p
xmlns:text="urn:oasis:names:tc:opendocument:xmlns:text:1.0">1</text:p></table:table-cell>
>> cl.getValueType
ans =
FLOAT
>> cl.getValue
ans =
1
>> 


...where I would expect "cl.getValue" to return something like
<java.math.BigDecimal> rather than a number, like Octave does:

debug> scell.getValue ()
ans =
<Java object: java.math.BigDecimal>



OK, I'll close this report again.
Sorry for the noise, thanks for your attention.
