The result of the example is 01:40 or 1 hour and 40 minutes.</paragraph> <paragraph role="paragraph" id="par_id3145271" xml-lang="en-US">In the formula, an entire 24-hour day has a value of 1 and one hour has a value of 1/24. The logical value in parentheses is 0 or 1, corresponding to 0 or 24 hours. The result returned by the formula is automatically issued in time format due to the sequence of the operands.</paragraph> <section id="relatedtopics"> <embed href="text/scalc/guide/calc_date.xhp#calc_date"/> </section> </body> </helpdocument>
