Another useful toplevel object to know about is the WorksheetFunction
object. That object provides the functions from the Excel formula bar to your Visual Basic code. Some of these members
are redundant with those provided by the VBA object library, however, others provide very useful (and advanced) analytical and statistical functions, as described in Table 48.
