RooAbsBinning* _binning
This class also holds an error and a fit range associated with the real value
RooRealVar()
Default constructor
RooRealVar(const char *name, const char *title,
Double_t value, const char *unit) :
RooAbsRealLValue(name, title, unit), _error(-1), _asymErrLo(1), _asymErrHi(-1) //, _fitBins(100)

Double_t minValue, Double_t maxValue,
const char *unit) :
RooAbsRealLValue(name, title, unit), _error(-1), _asymErrLo(1), _asymErrHi(-1) // , _fitBins(100)
Constructor with range and unit. Value is set to middle of range
RooRealVar(const char *name, const char *title,
Double_t value, Double_t minValue, Double_t maxValue,
const char *unit) :
RooAbsRealLValue(name, title, unit), _error(-1), _asymErrLo(1), _asymErrHi(-1) //, _fitBins(100)

const RooAbsBinning& getBinning(const char* name, Bool_t verbose, Bool_t createOnTheFly) const
RooAbsBinning& getBinning(const char* name, Bool_t verbose, Bool_t createOnTheFly)

Bool_t readFromStream(istream& is, Bool_t compact, Bool_t verbose)
Read object contents from given stream
void writeToStream(ostream& os, Bool_t compact) const
Write object contents to given stream
void printToStream(ostream& os, PrintOption opt, TString indent) const
Print info about this object to the specified stream. In addition to the info
from RooAbsRealLValue::printToStream() we add:
Verbose : fit range and error

TString* format(Int_t sigDigits, const char *options) const
Format numeric value in a variety of ways
What is shown?
N = show name
H = hide value
E = show error
A = show asymmetric error instead of parabolic error (if available)
U = show unit
How is it shown?
L = TLatex mode
X = Latex mode
Y = Latex table mode ( '=' replaced by '&' )
V = Make name \verbatim in Latex mode
P = use error to control shown precision
F = force fixed precision
