Help with Formula field

Help with Formula field

I designed a formula field to calculate age of account but I made it with String output so I can add the word "Years" to the end. However the out put of the formula comes with up to 16 decimal points which I only want two decimal points to come out. what other formula can I add to this   

Concat(Tostring(Datecomp(Now(),${Contact Positive Accounts.Date Opened})/(60*24*365)),' ','Years')

To limit the out put to two decimal points
This is the current output
1.1315068493150684 Years
I need it to just display

1.13 Years


Any help will be greatly appreciated
