Macro Help

Ok Macro gurus (of which I am not).
I found some macros on Matt Lombard's site (http://mysite.verizon.net/mjlombard/)that changes decimal placs to 2,3, or 4 plces.
I don't know the codes to modify this and was hoping that someoneelse could.
I would like it to chage decimal places for dual dimension.
EX..xx (standard)
.x (metric)
and
.xxx (english)(standard)
.xx (metric)

Does anyone have something similar that they could shareSolidworksDrawings And Detailing
