Prerequisite

• Unit
• Quantum

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:

• Straight comparisons: unequal if non-conforming units or different values
• Comparisons
• Special make Bool routines to cater for array comparisons

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

Member Function Documentation

template<class Qtype >

Bool casa::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.

Thrown Exceptions

• AipsError if non-conforming units
