324      *

326      * http://msdn.microsoft.com/library/en-us/office97/html/SEB7C.asp
327      * is _not_ the way how it is actually calculated by Excel (that would not
328      * even match any of the 7 methods mentioned above) and would result in the
329      * following test cases producing wrong results according to that appendix B:
330      *
331      * 28-Feb-95  31-Aug-95  181 instead of 180
332      * 29-Feb-96  31-Aug-96  181 instead of 180
333      * 30-Jan-96  31-Mar-96   61 instead of  60
334      * 31-Jan-96  31-Mar-96   61 instead of  60
335      *
336      * Still, there is a difference between OOoCalc and Excel:
337      * In Excel:
338      * 02-Feb-99 31-Mar-00 results in  419
339      * 31-Mar-00 02-Feb-99 results in -418
340      * In Calc the result is 419 respectively -419. I consider the -418 a bug in Excel.

1579 /** (Goal Seek) Find a value of x that is a root of f(x)
1580 
1581     This function is used internally for the goal seek operation.  It uses the
1582     Regula Falsi (aka false position) algorithm to find a root of f(x).  The
1583     start value and the target value are to be given by the user in the
1584     goal seek dialog.  The f(x) in this case is defined as the formula in the
1585     formula cell minus target value.  This function may also perform additional
1586     search in the horizontal directions when the f(x) is discrete in order to
1587     ensure a non-zero slope necessary for deriving a subsequent x that is
1588     reasonably close to the root of interest.
