I am trying to create a UDF that executes the following formula but I am unsure how exactly to structure the code for UDFs, more up to speed on run-of-the-way VBA macros. Any guidance would be appreciated.

=LEFT(XX,FIND("-",XX)-1)+SUBSTITUTE(RIGHT(XX,LEN(XX)-FIND("-",XX)),"+","")/32+IF(RIGHT(RIGHT(XX,LEN(XX)-FIND("-",XX)),1)="+",1/64,0)
 

Excel Facts

What do {} around a formula in the formula bar mean?
{Formula} means the formula was entered using Ctrl+Shift+Enter signifying an old-style array formula.
Try this

Code:
Function formulaXX(c As Range)
  formulaXX = Evaluate(Replace("=LEFT(@,FIND(""-"",@)-1)+" & _
      "SUBSTITUTE(RIGHT(@,LEN(@)-FIND(""-"",@)),""+"","""")/32+" & _
      "IF(RIGHT(RIGHT(@,LEN(@)-FIND(""-"",@)),1)=""+"",1/64,0)", "@", c.Address))
End Function

Example to use:

=formulaXX(B3)
