  This is test output of the \textsf{ionumbers} \LaTeX{} package. The default
  \LaTeX{} output, the output with \textsf{ionumbers} package and the expected
  output with \textsf{ionumbers} package is given for different inputs.
  If the package \textsf{ionumbers} works correctly, the contents in the
  `\textsf{ionumbers}' columns and the respective contents in the `expected'
  columns must be identical.
  Note that a lot of input is nonsense and serves for testing purposes only.
