Dear Christopher, Thank you for reporting this problem. It turns out this is platform dependent. I found strange behavior of ios::setf() in UNIX platforms. Here is the solution. Please edit $CINTSYSDIR/include/iostream.h as follows. You need to add unsetf() calls. This source is interpreted so you do not need to recompile anything. Thank you Masaharu Goto --------- $CINTSYSDIR/include/iostream.h from line 446 -------------- class G__CINT_HEX { int dmy; } hex; ostream& operator<<(ostream& ostr,G__CINT_HEX& i) { ostr.unsetf(ios::dec); ostr.unsetf(ios::oct); ostr.setf(ios::hex); return(ostr); } istream& operator>>(istream& istr,G__CINT_HEX& i) { ostr.unsetf(ios::dec); ostr.unsetf(ios::oct); istr.setf(ios::hex); return(istr); } class G__CINT_DEC { int dmy; } dec; ostream& operator<<(ostream& ostr,G__CINT_DEC& i) { ostr.unsetf(ios::hex); ostr.unsetf(ios::oct); ostr.setf(ios::dec); return(ostr); } istream& operator>>(istream& istr,G__CINT_DEC& i) { ostr.unsetf(ios::hex); ostr.unsetf(ios::oct); istr.setf(ios::dec); return(istr); } class G__CINT_OCT { int dmy; } oct; ostream& operator<<(ostream& ostr,G__CINT_OCT& i) { ostr.unsetf(ios::hex); ostr.unsetf(ios::dec); ostr.setf(ios::oct); return(ostr); } istream& operator>>(istream& istr,G__CINT_OCT& i) { ostr.unsetf(ios::hex); ostr.unsetf(ios::dec); istr.setf(ios::oct); return(istr); } ======================================================================== Could someone else try this and let me know if you get the same result, so I can find out if it's just me or not. root [1] int a=20; root [2] cout << hex << a << endl; 20 (not 14 hex as expected) root [3] cout.setf(ios::hex); root [4] cout << a << endl; 20 (again not 14 hex as expected) Using ROOT 2.22/10 with CINT 5.14.10 under Redhat 6.0. Thanks. P.S. If questions like this, about CINT, are not approved on this mail list, let me know that too, so I can look elsewhere for an answer. -- Christopher A.
