pt-table-sync now uses up to 17 decimal digits when writing floating point numbers in the generated SQL statements. This is necessary to prevent unintended data changes.

The tests added with
pt-2378.tall fail with the current code base. With the proposed change, they run successfully. They test that bothREPLACEandUPDATEstatements are generated bypt-table-syncsuch that floating point numbers that are not intended to change indeed don't change.The code is my own creation and it can be distributed under the GPL2 licence.
