<paragraph role="paragraph" id="par_id11641927688319"><emph>Number:</emph> The number to be rounded down.</paragraph>
<paragraph role="paragraph" id="par_id861641927715672"><emph>Count:</emph> Optional parameter that defines the number of decimal places to be kept. The default value is 0 (zero).</paragraph>
<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>
</section>
<note id="par_id181641929609906">In %PRODUCTNAME, the <emph>Count</emph> parameter is optional, whereas in Microsoft 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>

<paragraph role="paragraph" id="par_id901641928192870"><input>=ROUNDDOWN(21.89)</input> returns 21. Note that this example uses the default value for <emph>Count</emph> which is 0.</paragraph>
<paragraph role="paragraph" id="par_id901641928192110"><input>=ROUNDDOWN(103.37,1)</input> returns 103.3.</paragraph>
<paragraph role="paragraph" id="par_id171641928456743"><input>=ROUNDDOWN(0.664,2)</input> returns 0.66.</paragraph>
<paragraph role="paragraph" id="par_id641641928712287"><input>=ROUNDDOWN(214.2,-1)</input> returns 210. Note the negative value for <emph>Count</emph>, which causes the first integer value before the decimal separator to be rounded towards zero.</paragraph>
