Number::Latin is a Perl module that can convert to/from the number system "a,b,...z,aa,ab..."

SYNOPSIS

use Number::Latin;
print join( , map int2latin($_), 1 .. 30), "n";
#
# Prints:
# a b c d e f g h i j k l m n o p q r s t u v w x y z aa ab ac ad

Some applications, notably the numbering of points in outlines, use a scheme that starts with the letter "a", goes to "z", and then starts over with "aa" thru "az", then "ba", and so on. (The W3C refers to this numbering system as "lower-latin"/"upper-latin" or "lower alpha"/"upper alpha", in discussions of HTML/CSS options for rendering of list elements (OL/LI).)

This module provides functions that deal with that numbering system, converting between it and integer values.

FUNCTIONS

This module exports four functions, int2latin, int2Latin, int2LATIN, and latin2int:

$latin = int2latin( INTEGER )

This returns the INTEGERth item in the sequence (a .. z, aa, ab, etc). For example, int2latin(1) is "a", int2latin(2) is "b", int2latin(26) is "z", int2latin(30) is "ad", and so for any nonzero integer.

$latin = int2Latin( INTEGER )

This is just like int2latin, except that the return value is has an initial capital. E.g., int2Latin(30) is "Ad".

$latin = int2LATIN( INTEGER )

This is just like int2latin, except that the return value is in all uppercase. E.g., int2LATIN(30) is "AD".

$latin = latin2int( INTEGER )

This converts back from latin number notation (regardless of capitalization!) to an integer value. E.g., latin2int("ad") is 30.

Number::Phone::IE is a Perl module with Republic of Ireland-specific methods for Number::Phone.
SYNOPSIS
use Number::Phone;
$dermots_phone = Number::Phone->new(IE, 017654321);
METHODS
The following methods from Number::Phone are overridden:
is_valid
The number is valid within the national numbering scheme. It may or may not yet be allocated, or it may be reserved. Any number which returns true for any of the following methods will also be valid.
is_allocated
The number has been allocated to a telco for use. It may or may not yet be in use or may be reserved. Not currently implemented.
is_geographic
The number refers to a geographic area.
is_fixed_line
The number, when in use, can only refer to a fixed line.
is_mobile
The number, when in use, can only refer to a mobile phone.
is_pager
The number, when in use, can only refer to a pager.
is_tollfree
Callers will not be charged for calls to this number under normal circumstances.
is_specialrate
The number, when in use, attracts special rates. For instance, national dialling at local rates, or premium rates for services.
is_adult
The number, when in use, goes to a service of an adult nature, such as porn.
is_network_service
The number is some kind of network service such as a human operator, directory enquiries, emergency services etc
country_code
Returns 353.
regulator
Returns some text in an appropriate character set saying who the telecoms regulator is, with optional details such as their web site or phone number.
areacode
Return the area code - if applicable - for the number. If not applicable, returns undef.
areaname
Return the area name - if applicable - for the number, or undef.
subscriber
Return the subscriber part of the number
operator
Return the name of the telco operating this number, in an appropriate character set and with optional details such as their web site or phone number. Not currently implemented.
format
Return a sanely formatted version of the number, complete with IDD code, eg for the Irish number (021) 765-4321 it would return +353 21 7654321.
country
If the number is_international, return the two-letter ISO country code.
NYI
Version restrictions:
- Strictly sppeaking, this kind of duplication of the Number::Phone::UK class is bad. A tidy-up is in order, though it may emerge that a completely new implemantation is better.
- The results are only as accurate as my own investigations into current allocations. User feedback welcome.
- While the names of the nominal owners of mobile prefixes are given, number portability makes this information unreliable.

Number::Encode is a Perl module to encode bit strings into digit strings.

SYNOPSIS

use Number::Encode qw(nonuniform uniform);

Provides a mechanism to convert arbitrary bit-strings into numeric digit strings. The transformation can be uniform or non-uniform depending on the type of distribution of the numeric digits achieved.

The former approach is useful for security-related applications such as calling cards and the such, which require a uniform digit distribution. The algorythm used to generate uniform distributions, while deterministic, is more constly than the non-uniform variant.

This module is distributed under the same terms and warranty as Perl itself.

Scalar::Number is a Perl module with numeric aspects of scalars.

SYNOPSIS

use Scalar::Number qw(scalar_num_part);

$num = scalar_num_part($scalar);

use Scalar::Number qw(sclnum_is_natint sclnum_is_float);

if(sclnum_is_natint($value)) { ...
if(sclnum_is_float($value)) { ...

use Scalar::Number qw(sclnum_val_cmp sclnum_id_cmp);

@sorted_nums = sort { sclnum_val_cmp($a, $b) } @floats;
@sorted_nums = sort { sclnum_id_cmp($a, $b) } @floats;

This module is about the numeric part of plain (string) Perl scalars. A scalar has a numeric value, which may be expressed in either the native integer type or the native floating point type. Many values are expressible both ways, in which case the exact representation is insignificant. To fully understand Perl arithmetic it is necessary to know about both of these representations, and the differing behaviours of numbers according to which way they are expressible.
This module provides functions to extract the numeric part of a scalar, classify a number by expressibility, and compare numbers across representations.

slsnif is a serial line sniffer. It listens to the specified serial port and logs all data coming through it. slsnif works transparently for both the device connected to the serial port and the controlling software for this device. It operates by opening a pseudo tty (pty) and linking it to the actual serial port.
slsnif operates by opening a pty and linking it to the serial port. These are following parameters / options:
1. Serial port to open (required).
2. Name of the file to direct output to (optional, defaults to stdout).
3. Desired baudrate (optional, defaults to 9600 baud).
4. Timestamp On/Off (optional, defaults to Off).
5. Print ascii values in hex On/Off (optional, defaults to Off)
6. Print number of bytes transmitted On/Off (optional, defaults to Off).
7. Optional colors for timestamp, number of bytes transmitted and normal output.
8. Lock port On/Off (optional, defaults to On).
9. Use Unix98 ptys instead of BSD ptys (optional, defaults to BSD style).
10. Second serial port to open. If specified, this port will be used instead of a pty, thus providing an ability to log data between two serial ports.
Enhancements:
- Added ability to resynchronize ports at any time by sending a SIGUSR1 signal to slsnif. Useful for debugging applications that change port parameters mid-way, after starting the transmission. One example is pppd daemon, which sets initial parameters in the chat script, and changes them later, after chat script terminates.
- Added ability to use SYSV (Unix98) ptys instead of BSD ones (see -u and --unix98 parameters). This option can also be turned on/off from rc-file.

Approximator Line is an application which allows to synthesize approximation function of one argument. Both coordinates of known points or mathematical expression can be used as input data.
The application uses evolutionary algorithm which allows to find more optimal results. The enhanced evolutionary algorithm allows to avoid long-time hitting to local maximum.
In few hours the application can evaluate milliards of combinations with using of reasonable number of input data points and on contemporary computer. Approximator Line uses multithreading that can help to utilize maximum computation power.
Approximator Lines primary goal is to search of function, which value, most come nearer to the initial data. The preference is given the smallest functions. The weight of this preference is established in options of synthesis.
Search of function is made by the next way:
The random mathematical variant is under construction. Its fitness to the data is calculated. Further the variant is copied and changes. Fitness of the changed variant is calculated. If it is more, the new variant becomes base. It is simplified.
Key parameter of the found function is fitness of its set goal. Fitness is expressed in percentage. Its value depends on a way of the assignment of fitness of a point (it is established in parameters of synthesis). The program uses two basic such as fitness:
General fitness
Calculates on the general points.
Additional fitness
Calculates on general and additional points. It is used for more exact definition of fitness. It also is used for avoidance of a finding of such functions which correspond to the basic points, but in an interval between them strongly differ.
Additional fitness is used for a finding of the most corresponding functions at smaller amount of computing expenses as it calculates only if the basic fitness more than at the previous variant. Besides each of the mentioned above fitness can be normal or effective.
Normal fitness
Fitness in view of amount of elements of expression.
Effective fitness
Fitness without taking into account amount of elements of expression.
In the list of results normal additional conformity and effective additional conformity is accordingly displayed.
By search of the most suitable variant, or in other words synthesis cancelation constant subexprassions is made also.
Synthesis is based on use of random numbers. Functions making expression, operators variables and numbers get out randomly. The application is optimized on speed. So synthesized function in memory represents a tree of mathematical objects. Values of function are calculates by the most effective way. The mutation also is made above a tree of objects.
Usage:
- Determine the form of the input data (coordinates or expression).
- Choose points of your graph. Synthesis will be estimated on them.
- Enter coordinates of points (use autonumbering for simplification of input) or expression.
- Determine a range of value of function, amount of the basic points, amount of additional points.
- Open parameters of synthesis and adjust if it is necessary.
- Save the project.
- Press Start of synthesis.
- Pass to results and see on them.
- Leave the application working on long time.
- Periodically check results. When the application will find, in your opinion, suitable function, press Stop and save results.
