This would be the analogue of ToExpression[ > some_string_representing_a_number ]. Assuming I have correctly guessed how you could possibly use (incorrectly?) *PaddedForm*, you can use *First* to extract the original number. (Use FullForm[y] to see the structure of y.) For instance, In[1]:= y = PaddedForm[1.23456, {3, 4}] Out[1]//PaddedForm= \!\(\* TagBox[ InterpretationBox["\<\" 1.2300\"\>", 1.23456, AutoDelete->True], PaddedForm[#, {3, 4}]& ]\) In[2]:= % + 1000 == y + 1000 Out[2]= 1001.23 == 1000 + \!\(\* TagBox[ InterpretationBox["\<\" 1.2300\"\>", 1.23456, AutoDelete->True], PaddedForm[#, {3, 4}]& ]\) In[3]:= %% + 1000 == First @ y + 1000 Out[3]= True -- Jean-Marc
