Nice that it was useful!
Yes, I have one function for that, it's one of my favorites excel
ones. I leave it in my personal macro workbook, and have a special
keyboard shortcut for call it.
Pay attention for you decimal system separator. Here in Brazil we use
comma for decimal separator. You can change it in:
Replace(Format(v(r, C), "@"), ",", ".")
There is the VBA
