Etymology

QLogical derived from Quantum logical functions

Synopsis

Quantities are values with a unit. Their basic specification can be one of two forms:

Quantity(Double value, String unit); // or: Unit unit

Quantum<Type> (Type value, String unit) // or: Unit unit

A unit is a string of known unit fields separated by 'space' or '.' (to indicate multiply) or '/' (to indicate divide). See the Unit class for details. Example: km/s/(Mpc.s)2 is identical to km.s-1.Mpc-2.s-2

This file defines the logical operations that can be done on Quantum<T>.

They can be subdivided into various groupings:

The operations defined are:

Quantum<T> == Quantum<T> or ==T
Quantum<T> != Quantum<T> or !=T
> < >= <= of Quantum<T> or T and Quantum<T>
near, nearAbs(Quantum<T> or T, Quantum<T> or T [, tolerance])

Motivation

To separate the logical operations from Quantum

To Do

Some inlining (did not work first go)
Recode with allEQ etc if part of library for all data types, and get rid of the special QMakeBool(), and the include LogiArrayFwd.h

template<class Qtype >

Bool casacore::QLogical_global_functions_Quantum_logical_operations::near	(	const Quantum< Qtype > &	left,
		const Quantum< Qtype > &	other
	)

Near-ness tests: unequal if non-conforming units.

In other cases the tolerance is in the units of the first argument, with the second argument converted, if necessary, to the same units as the first. Note (SUN?) compiler does not accept default arguments in template functions

Comparisons.

The comparisons are done on values at equal units with transparent conversion if necessary.
