Converting numbers into string

Hi, I am looking for an easy way to convert numbers (Int_t, Double_t) into strings. What i want to do is to create dynamical columns in my ntuple and fill them. Something that should look like: string nameA=“ColumnNameA”, nameB=“ColumnNameB”; Int_t intA[42], intB[42]; //or Double_t … loop over x { intA[x] = 123; intA --> to string --> stringA _myTuple->column(nameA+stringA+"additionalString",(double) value); } Maybe somebody knows a nifty way to do something like that. Cheers & Than…
