RooRealVar Class Reference

RooRealVar represents a variable that can be changed from the outside.

For example by the user or a fitter.

It can be written into datasets, can hold a (possibly asymmetric) error, and can have several ranges. These can be accessed with names, to e.g. limit fits or integrals to sub ranges. The range without any name is used as default range.

If binning with 'name' is not found it is created on the fly as a clone of the default binning if createOnTheFly is true, otherwise a reference to the default binning is returned. If verbose is true a message is printed if a binning is created on the fly.
