DESCRIPTION
Nomenclature
Method naming conventions for Math::Logic::Ternary::Word are as follows:
 Logical operators

Elementary logical operators can be applied in two ways to word objects. Words can be treated as single trits, so that only their truth values (read: signs) are taken into account. Operators with all uppercase names will treat words in this way.
Logical operators spelled all lowercase, on the other hand, will work tritwise on all trits of their operands in parallel. The least significant trit of the result will be the result of the operation on the least significant trits of the operands, and so on up to the most significant trit.
If words of different sizes are mixed in an operation, the leftmost argument determines the word size in which the operation is carried out. Other operands will be padded with nil trits or truncated accordingly, aligned on their least significant end.
 Numerical operators

Numerical operators treat their operands as numerical values, which usually means that different trits in multitritwords interfere with each other in the course of a computation. Their names are written in mixed case starting with an uppercase letter.
Most numerical and some logical functions have different variants for balanced, unbalanced, and base(3) arithmetic, where unbalanced also means unsigned. Balanced ternary digits are 1, 0, and 1. Unbalanced base(3) and base(3) ternary digits are 0, 1, and 2. As balanced ternary numbers are in many cases easier to deal with than unbalanced or negative base numbers, our naming scheme prefers the former, giving balanced arithmetic operators short names, while their unbalanced counterparts get a suffix letter u or U, and base(3) operators v or V.
 Comparison functions

Comparisons are the ultimate challenge of standardizing ternary logic, since there are six ways to assign comparison results to trit values and six ways to order trit values. For threeway comparison results, we continue leaning towards balanced arithmetic and assign 1 (false) to "less than", 0 (nil) to "equal to" and 1 (true) to "greater than". We regard false < nil < true as the "natural" trit order, and nil < true < false as the "unbalanced" order. Again, the latter is flagged with a u or U suffix.
 Conversions

Conversions from objects to other data have a name prefix to_ or To_ depending on whether they convert a truth value or a word. The prefix is followed by a name for the data type they yield. If there is an unbalanced or base(3) variant the final suffix is _u or _v, respectively. Alien type names are always separated by underscores from prefixes and suffixes (if there are any).
Conversions from other data to objects have a name prefix from_ or From_ depending on whether they yield single trits or words, followed by a name for the data type they accept. Again, the unbalanced and base(3) suffixes are _u and _v, respectively. These constructors are class methods.
Conversions to and from floating point formats are not implemented here. A ternary floating point format with a whole bunch of operations and conversions is defined in the separate module Math::Logic::Ternary::TFP_81.
If an operand size does not match the word size of an operator, it is silently truncated to its least significant trits or padded with leading zeroes as appropriate.
Exports
None.
Complete list of methods
Logical and tritwise operators
Operators on trits are carried over to word objects in two variants.
Spelled all uppercase they act as pure logical operators, using just the truth values (read: signs) of their arguments and returning a trit.
Spelled all lowercase they act as tritwise operators, performing the logical operation on each trit position of the arguments, and returning a word.
The leftmost argument of a tritwise operator determines the word size of the operation and thus the size of the result. In tritwise operations, all arguments are aligned at the least significant end. Smaller arguments are padded with nil trits and larger arguments are truncated at the other end.
Details about trit operators are documented in Math::Logic::Ternary::Trit.

characters for all trits in the word including leading zeroes, from most to least significant trit, prepended by an@
sigil.  is_equal

$word>is_equal($obj)
returns true if$word>Rtrits
and$obj>Rtrits
are identical lists, otherwise false. This means that words of different sizes are regarded as equal if they represent equal numeric values.
Other Object Methods
 Mpx

Multiplex.
$word>Mpx($case_n, $case_t, $case_f)
with three arbitrary arguments returns$case_n
if$word
is zero,$case_t
if$word
is positive, or$case_f
if$word
is negative. Thus it is equivalent to$word>Sign
Mpx($case_n, $case_t, $case_f)>.  as_base27

$word>as_base27
returns a string of base(27) letters (_
, lower casea
up tom
, upper caseN
up toZ
) for all groups of three trits in the word including leading zeroes, from most to least significant triplet, prepended by a%
sigil. The most significant triplet will be taken as zero padded if the word size is not a multiple of three.Base(27) string representations of words of equal size will sort lexically in the same order as their balanced ternary values sort numerically. Zero values will yield a string of underscore characters, prepended by
%
.  as_modint
 as_modint_u
 as_modint_v

$word>as_modint
converts the numerical value of$word
to a Math::ModInt object modulo 3 ** n for words of size n, using balanced arithmetic. The variants as_modint_u and as_modint_v do the same in unbalanced and base(3) arithmetic.The Perl extension Math::ModInt (available on CPAN) must be installed for this to work, otherwise as_modint etc. will raise a runtime exception.

Class methods
Constructors
Word objects are fixed size containers for trits. All constructors take a size argument and additional information defining those trit values.
The size must be a positive integer. There may be an implementationspecific upper limit for the size. Sizes up to 3 ** 9
should always be valid, though.
 from_trits

Math::Logic::Ternary::Word
from_trits($size, @trits)> creates a new word object of given size from the given trit values.Trits must be enumerated from lowest to highest significance, without gaps. Trailing (i.e. highly significant) nil trits may be omitted. Trailing superfluous nil trits will be ignored. Nonnil trits beyond the given size will trigger an exception.
 from_words

Math::Logic::Ternary::Word>from_words($size, @words)
creates a new word object of given size from trit values taken from the given list of words.The words may be of any size and must be listed from lowest to highest significance. All of their trits are used.
 from_bools

Math::Logic::Ternary::Word>from_bools($size, @bools)
creates a new word object of given size from trit values given as booleans rather than trit objects. Boolean values are taken as nil if undefined, false if defined but false, or true if true.  from_int

creates a new word representing the given integer value in base(3) arithmetic. If the integer value exceeds the range of the given word size an exception is raised.  from_base27

Math::Logic::Ternary::Word>from_base27($size, $string)
creates a new word from a string of base(27) digits (underscore and letters, case not important), given in highest to lowest significance order. If the resulting value exceeds the range of the given word size an exception is raised. See also "as_base27".  from_string

Math::Logic::Ternary::Word>from_string($size, $string)
creates a new word from a string of ternary digits (n
,t
,f
, case not important), given in highest to lowest significance order. If the resulting value exceeds the range of the given word size an exception is raised.If the string begins with one of the sigils
%
,@
, or$
, it is interpreted as a base(27) string, ternary digit string, or single ternary digit name, respectively.If the string is not syntactically correct, an exception is raised.
 from_modint

Math::Logic::Ternary::Word>from_modint($size, $string)
creates a new word from a Math::ModInt object (i.e. a modular integer) representing the same value if interpreted as a balanced ternary number. The modulus must be a power of three. Size can be zero or the base 3 logarithm of the modulus, otherwise an exception will be raised.  from_modint_u

Math::Logic::Ternary::Word>from_modint_u($size, $string)
creates a new word from a Math::ModInt object (i.e. a modular integer) representing the same value if interpreted as an unsigned ternary number. The modulus must be a power of three. Size can be zero or the base 3 logarithm of the modulus, otherwise an exception will be raised.  from_modint_v

Math::Logic::Ternary::Word>from_modint_v($size, $string)
creates a new word from a Math::ModInt object (i.e. a modular integer) representing the same value if interpreted as a base(3) number. The modulus must be a power of three. Size can be zero or the base 3 logarithm of the modulus, otherwise an exception will be raised.  from_various

Math::Logic::Ternary::Word>from_various($size, @args)
creates a new word from its arguments, guided by their type. If the resulting value exceeds the range of the given word size an exception is raised.If the arguments are word or trit objects, they will be packed into a new word of the given size.
If the argument is a single string of decimal digits, optionally preceded by plus or minus, or it is a single Math::BigInt object, it will be converted as in from_int.
If the argument is a single Math::ModInt object, it will be converted as in from_modint.
If the arguments are plain perl scalars, they will be converted as in from_bools.
If the argument is a single string recognized by as_string, it will be converted accordingly.
Other class methods
 word_operators

Math::Logic::Ternary::Word>word_operators
returns a list of arrayrefs, each holding an operator signature with five attributes:  word_formatters
