gul17::StandardDeviationMean< DataT, typename > Class Template Reference

Detailed Description

template<typename DataT, typename = std::enable_if_t<std::is_floating_point<DataT>::value>>
class gul17::StandardDeviationMean< DataT, typename >

A struct holding a standard deviation and a mean value.

DataT must be a floating point type.

Default constructed the contained values are Not-a-Number.

The object can be cast to DataT in which case it is results in the sigma value. DataT is usually statistics_result_type.

The data members are public to allow structured bindings.

Template Parameters

DataT

Type of the contained values

auto	mean () const noexcept -> DataT
	Get the arithmetic mean value.

Public Attributes
DataT	sigma_ { NAN }
	The standard deviation (sigma) value.
DataT	mean_ { NAN }
	The mean value.
