Hi, i would like to do a bitmask operation on an integer in a TTree. for example: T.Draw("xyzD3 & 0x3ff") where i want to see the lower 10 bits of the integer xyzD3. Or even: T.Draw("xyzD3 % 1024") and T.Draw("xyzD3 / 1024") with their usual integer interpretations would be sufficient. Any suggestions on how to do this?
