If this is only for Print, you may try: In[51]:= a=5; b=Pi; c="what?"; In[54]:= Attributes[preventIntegerfromN]={NHoldAll, Listable} In[55]:= Format[preventIntegerfromN[i_Integer]]:=i In[56]:= preventIntegerfromN[else_/;Head[else]=!=Integer]:=else In[57]:= Print[{{"a","b","c"},{a,b,c}//N@preventIntegerfromN[#]&}//TableForm] >From In[57]:= \!\(\* TagBox[GridBox[{ {"\<\"a\"\>", "\<\"b\"\>", "\<\"c\"\>"}, {"5", "3.141592653589793`", "\<\"what?\"\>"} }, RowSpacings->1, ColumnSpacings->3, RowAlignments->Baseline, ColumnAlignments->{Left}], Function[ BoxForm`e$, TableForm[ BoxForm`e$]]]\) No decimal point after 5 ! -- Hartmut > -----Original Message----- > From: A.
