So for the cosine of 180 degrees you need "COS(RADIANS(180))" which gives the correct result -1. This is well documented in both the tooltip information for Calc functions, and Help documentation. I believe MS Excel has the same behavior. I know there is a bug with more detailed information on this bugzilla, but I can't find it right now. Regardless, this is either NOTABUG or WONTFIX.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
