49        Octonions, like <a href="quaternions.html" title="Quaternions">quaternions</a>,
50        are a relative of complex numbers.
51      </p>
52<p>
53        Octonions see some use in theoretical physics.
54      </p>
55<p>
56        In practical terms, an octonion is simply an octuple of real numbers (
57&#945;,&#946;,&#947;,&#948;,&#949;,&#950;,&#951;,&#952;
58        ), which we can write in the form <span class="emphasis"><em><code class="literal">o =
59&#945; + &#946;i + &#947;j + &#948;k + &#949;e' + &#950;i' + &#951;j' + &#952;k'
60        </code></em></span>, where <span class="emphasis"><em><code class="literal">i</code></em></span>,
61        <span class="emphasis"><em><code class="literal">j</code></em></span> and <span class="emphasis"><em><code class="literal">k</code></em></span>
62        are the same objects as for quaternions, and <span class="emphasis"><em><code class="literal">e'</code></em></span>,
63        <span class="emphasis"><em><code class="literal">i'</code></em></span>, <span class="emphasis"><em><code class="literal">j'</code></em></span>
64        and <span class="emphasis"><em><code class="literal">k'</code></em></span> are distinct objects which
65        play essentially the same kind of role as <span class="emphasis"><em><code class="literal">i</code></em></span>
66        (or <span class="emphasis"><em><code class="literal">j</code></em></span> or <span class="emphasis"><em><code class="literal">k</code></em></span>).
67      </p>
68<p>
69        Addition and a multiplication is defined on the set of octonions, which generalize
70        their quaternionic counterparts. The main novelty this time is that <span class="bold"><strong>the multiplication is not only not commutative, is now not even
71        associative</strong></span> (i.e. there are quaternions <span class="emphasis"><em><code class="literal">x</code></em></span>,
72        <span class="emphasis"><em><code class="literal">y</code></em></span> and <span class="emphasis"><em><code class="literal">z</code></em></span>
73        such that <span class="emphasis"><em><code class="literal">x(yz)
74&#8800;
75        (xy)z</code></em></span>). A way of remembering things is by using the
76        following multiplication table:
77      </p>
78<p>
79        <span class="inlinemediaobject"><img src="../../../libs/math/octonion/graphics/octonion_blurb17.jpeg" alt="octonion_blurb17"></span>
80      </p>
81<p>
82        Octonions (and their kin) are described in far more details in this other
83        <a href="../../../libs/math/quaternion/TQE.pdf" target="_top">document</a> (with <a href="../../../libs/math/quaternion/TQE_EA.pdf" target="_top">errata and addenda</a>).
84      </p>
85<p>
86        Some traditional constructs, such as the exponential, carry over without
87        too much change into the realms of octonions, but other, such as taking a
88        square root, do not (the fact that the exponential has a closed form is a
89        result of the author, but the fact that the exponential exists at all for
90        octonions is known since quite a long time ago).

561        A default constructor is provided for each form, which initializes each component
562        to the default values for their type (i.e. zero for floating numbers). This
563        constructor can also accept one to eight base type arguments. A constructor
564        is also provided to build octonions from one to four complex numbers sharing
565        the same base type, and another taking one or two quaternions sharing the
566        same base type. The unspecialized template also sports a templarized copy
567        constructor, while the specialized forms have copy constructors from the
568        other two specializations, which are explicit when a risk of precision loss
569        exists. For the unspecialized form, the base type's constructors must not
570        throw.
571      </p>
572<p>
573        Destructors and untemplated copy constructors (from the same type) are provided
574        by the compiler. Converting copy constructors make use of a templated helper
575        function in a "detail" subnamespace.

590        Like complex number, octonions do have a meaningful notion of "real
591        part", but unlike them there is no meaningful notion of "imaginary
592        part". Instead there is an "unreal part" which itself is a
593        octonion, and usually nothing simpler (as opposed to the complex number case).
594        These are returned by the first two functions.

1001        These build octonions in a way similar to the way polar builds complex numbers,
1002        as there is no strict equivalent to polar coordinates for octonions.

1005        <code class="computeroutput"><span class="identifier">spherical</span></code> is a simple transposition
1006        of <code class="computeroutput"><span class="identifier">polar</span></code>, it takes as inputs
1007        a (positive) magnitude and a point on the hypersphere, given by three angles.
1008        The first of these, <span class="emphasis"><em>theta</em></span> has a natural range of -pi
1009        to +pi, and the other two have natural ranges of -pi/2 to +pi/2 (as is the
1010        case with the usual spherical coordinates in <span class="emphasis"><em><span class="bold"><strong>
1011R<sup>3</sup>
1012        </strong></span></em></span>). Due to the many symmetries and periodicities, nothing
1013        untoward happens if the magnitude is negative or the angles are outside their
1014        natural ranges. The expected degeneracies (a magnitude of zero ignores the
1015        angles settings...) do happen however.
1016      </p>
1017<p>
1018        <code class="computeroutput"><span class="identifier">cylindrical</span></code> is likewise a
1019        simple transposition of the usual cylindrical coordinates in <span class="emphasis"><em><span class="bold"><strong>
1020R<sup>3</sup>
1021        </strong></span></em></span>, which in turn is another derivative of planar polar
1022        coordinates. The first two inputs are the polar coordinates of the first
1023        <span class="emphasis"><em><span class="bold"><strong>C</strong></span></em></span> component of the
1024        octonion. The third and fourth inputs are placed into the third and fourth
1025        <span class="emphasis"><em><span class="bold"><strong>R</strong></span></em></span> components of the
1026        octonion, respectively.
1027      </p>
1028<p>
1029        <code class="computeroutput"><span class="identifier">multipolar</span></code> is yet another
1030        simple generalization of polar coordinates. This time, both <span class="emphasis"><em><span class="bold"><strong>C</strong></span></em></span> components of the octonion are given
1031        in polar coordinates.
1032      </p>
1033<p>
1034        In this version of our implementation of octonions, there is no analogue
1035        of the complex value operation arg as the situation is somewhat more complicated.

1042        There is no <code class="computeroutput"><span class="identifier">log</span></code> or <code class="computeroutput"><span class="identifier">sqrt</span></code> provided for octonions in this implementation,
1043        and <code class="computeroutput"><span class="identifier">pow</span></code> is likewise restricted
1044        to integral powers of the exponent. There are several reasons to this: on
1045        the one hand, the equivalent of analytic continuation for octonions ("branch
1046        cuts") remains to be investigated thoroughly (by me, at any rate...),
1047        and we wish to avoid the nonsense introduced in the standard by exponentiations
1048        of complexes by complexes (which is well defined, but not in the standard...).
1049        Talking of nonsense, saying that <code class="computeroutput"><span class="identifier">pow</span><span class="special">(</span><span class="number">0</span><span class="special">,</span><span class="number">0</span><span class="special">)</span></code> is "implementation
1050        defined" is just plain brain-dead...
1051      </p>
1052<p>
1053        We do, however provide several transcendentals, chief among which is the
1054        exponential. That it allows for a "closed formula" is a result
1055        of the author (the existence and definition of the exponential, on the octonions
1056        among others, on the other hand, is a few centuries old). Basically, any
1057        converging power series with real coefficients which allows for a closed
1058        formula in <span class="emphasis"><em><span class="bold"><strong>C</strong></span></em></span> can be
1059        transposed to <span class="emphasis"><em><span class="bold"><strong>O</strong></span></em></span>. More
1060        transcendentals of this type could be added in a further revision upon request.
1061        It should be noted that it is these functions which force the dependency
1062        upon the <a href="../../../boost/math/special_functions/sinc.hpp" target="_top">boost/math/special_functions/sinc.hpp</a>

1160        test program tests octonions specialisations for float, double and long double

1164        If you define the symbol BOOST_OCTONION_TEST_VERBOSE, you will get additional
1165        output (<a href="../../../libs/math/octonion/output_more.txt" target="_top">verbose output</a>);
1166        this will only be helpfull if you enable message output at the same time,
1167        of course (by uncommenting the relevant line in the test or by adding --log_level=messages
1168        to your command line,...). In that case, and if you are running interactively,
1169        you may in addition define the symbol BOOST_INTERACTIVE_TEST_INPUT_ITERATOR
1170        to interactively test the input operator with input of your choice from the
1171        standard input (instead of hard-coding it in the test).
