Maybe the mistake is in search for 0.000, it can't be found, because a
0.000 is always saved as 0, nonsignificant zeroes to the right/left of
decimal point are never saved.

Computers store numbers in a fixed-length format - however-many bytes.
So there are always the same number of binary digits stored - which
equates to a different but similarly (approximately) fixed number of
decimal digits stored (unless you choose multiple precision, of course).
So surely what you may think of as nonsignificant zeroes are not "never"
but *always* stored?

I think not a fixed format, but a fixed length with eight bytes used to store the number in memory, as result fourteen significant numbers.

In any case the user can't find 0.0000 or 000.00, we can search for 0.

In content.xml file one of the files in .ods file, we can see the saved values in office:value tag and the representation of the value in text:p tag.
