Subject: tests: Handle double values precision changes in SQLite 3.53.1
MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

The release news of this SQLite version (https://sqlite.org/releaselog/3_53_1.html)
has the following item:

9. Improvements to floating-point ↔ text conversions.
   a. Reimplemented to improve performance.
   b. Rounding is now done by default to 17 significant digits, instead
      of 15, as was the case for all prior versions. The
      sqlite3_db_config(SQLITE_DBCONFIG_FP_DIGITS) API (item 6g above)
      can change this, if desired.

This is generally great, but these precision changes seep in our
test suite. Adapt the SPARQL query tests that are returning double
values so that these are converted to a string up to a precision defined
in the query itself, and less dependent on implementation details.

Ideally, these tests should use cursor getters for double values and
compare with an epsilon, instead of these rough string comparisons we
do. This is left as something for the future.

(cherry picked from commit 47d5bf9313d0ccb1feb7169eed9047d0e1597a39)

Origin: upstream, after 3.11.1
