Detailed Description

template<class AccumType>
class casacore::StatsHistogram< AccumType >

Represents an unfilled histogram with equal width bins for binning used for quantile computations.

It is necessary to store the min/max values of the bin limits, because machine precision issues when the bin width is sufficiently small can cause slightly different results for these when different methods are used to compute them, leading to accounting errors when the histogram is filled with data.

template<class AccumType >

casacore::StatsHistogram< AccumType >::StatsHistogram	(	AccumType	minLimit,
		AccumType	maxLimit,
		uInt	nBins
	)

Construct a histogram by specifying its minimum and maximum values and the number of desired bins.

No padding of the min/max values is done internally, so the caller should do that prior to construction if necessary.

This does the obvious conversions.

The Complex and DComplex specializations (implemented below after the close of the class definition) are used solely to permit compilation. In general, those versions should never actually be called
