Sorry all but the title probably doesnt really explain the question properly

What id like to do to limit the amount of decimals in my answer

below is my formula.

="Overall Comex FPN's running at "&E29&" average based on above figures"

E29 = 2.8447477557
but shows as 2.84% in the cell

and this is what is comes out as

="Overall Comex FPN's running at 2.8447477557 average based on above figures"

id like it to just say

="Overall Comex FPN's running at 2.84% average based on above figures"

any help would be greatly appriciated.
