Sounds like a job for a procedure:
    ReturnData = ReEditNum (InputString : VaryingLength : DecLength)

The procedure could using %DECH(inputString:31:9) into a zoned subfield
and then do substringing on the data structure.  Since you're using the
X edit code, I assume you don't care about the difference between 1.2
and 12.  If so, you could XLATE out the decimal point and use
%DEC(string : 31 : 0).
        ReturnData = %Subst(%Editc(%Dec(%Xlate('.':' ':string) : 31 : 0)
: 'X') : 31 - VaryingLength + 1)
(Ewww ...)

By the way, %DECH handles decimal strings better than atof(), especially
if you suspect invalid data.  atof() doesn't give an error, it just
takes what it can use and ignores the rest.
