If a VBA function that’s equivalent to one you use in Excel is not available, you can use Excel’s worksheet functions directly in your VBA code. Just precede the function with a reference to the WorksheetFunction object. For example, VBA does not have a function to convert radians to degrees. Because Excel has a worksheet function for this procedure, you can use a VBA instruction such as the following:

Deg = Application.WorksheetFunction.Degrees(3.14)

The WorksheetFunction object was introduced in Excel 97. For compatibility with earlier versions of Excel, you can omit the reference to the WorksheetFunction object and write an instruction such as the following:

Deg = Application.Degrees(3.14)
