    <paragraph role="paragraph" id="par_id911641928545976">Use negative values for <emph>Count</emph> to round the integer part of the original <emph>Number</emph>. For example, -1 will round down the first integer number before the decimal separator, -2 will round down the two integer numbers before the decimal separator, and so forth.</paragraph>

  <note id="par_id181641929609906">In %PRODUCTNAME the <emph>Count</emph> parameter is optional whereas in MS Excel this parameter is mandatory. When an ODS file contains a call to ROUNDDOWN without the <emph>Count</emph> parameter and the file is exported to XLS or XLSX formats, the missing argument will automatically be added with value zero to maintain compatibility.</note>
