[Full Changelog](py-pdf/pypdf@3.4.0...3.4.1)

Version 3.4.0, 2023-02-05

NOTICE: pypdf changed the way it represents numbers parsed from PDF files.
  pypdf<3.4.0 represented numbers as Decimal, pypdf>=3.4.0 represents them as
  floats. Several other PDF libraries to this, as well as many PDF viewers.
  We hope to fix issues with too high precision like this and get a speed boost.
  In case your PDF documents rely on more than 18 decimals of precision you
  should check if it still works as expected.
  To clarify: This does not affect the text shown in PDF documents. It affects
  numbers, e.g. when graphics are drawn on the PDF or very exact positions are
  used. Typically, 5 decimals should be enough.
