Instead do TCut mycut(Form("phi <= %g", phiCut)); much simpler, much more C++-like, though the best thing would probably something like TString cutStr; cutStr << "phi=" << setprecision(10) << setw(20) << phiCut; Yours, Christian Holm Christensen ------------------------------------------- Address: Sankt Hansgade 23, 1. th.
