[Octave-bug-tracker] [bug #51178] publish() sometimes removes last element from vector after section break

Follow-up Comment #4, bug #51178 (project octave):

Checking with the wikipedia article on the IEEE-754 standard
(https://en.wikipedia.org/wiki/Double-precision_floating-point_format), I find
that precision is 15-17 decimal digits.  If Octave wants to *guarantee*
lossless save/restore of values in text format it needs to be keeping 17
digits.  See the quote below.


This gives 15–17 significant decimal digits precision. If a decimal string
with at most 15 significant digits is converted to IEEE 754 double precision
representation and then converted back to a string with the same number of
significant digits, then the final string should match the original. If an
IEEE 754 double precision is converted to a decimal string with at least 17
significant digits and then converted back to double, then the final number
must match the original.
