template<int DIMENSIONS>
class ROOT::Experimental::Detail::THistImplPrecisionAgnosticBase< DIMENSIONS >

Base class for THistImplBase that abstracts out the histogram's PRECISION.

For operations such as painting a histogram, the PRECISION (type of the bin content) is not relevant; painting will cast the underlying bin type to double. To facilitate this, THistImplBase itself inherits from the THistImplPrecisionAgnosticBase interface.
