I have a string, such as "msl=30mk/kg". I want to reorganize it to "30
(msl)". but the troubles are that the digits of number (30) is not stable,
this time 30, that time 40.89, maybe next time whatever it want to be.
Besides, the unit "mk/kg" is not stable, either.

till now, I have wrotten the following function. but the troubles listed
upon can't be solved yet. who can help me?

=MID(A1,FIND("=",A1,1)+1,2) & " (" & MID(A1,1,FIND("=",A1,1)-1) & ")"
