This package transparently speeds up functions by caching return values, trading space for time.

Data::Float is about the native floating point numerical data type. A floating point number is one of the types of datum that can appear in the numeric part of a Perl scalar. This module supplies constants describing the native floating point type, classification functions and functions to manipulate floating point values at a low level.

This is a CPAN Perl module that verifies the solutions of various variants of card Solitaire. It does not aim to try to be a solver for them, because this is too CPU intensive to be adequately done using perl5 (as of perl-5.10.0). Instead, what Games-Solitaire-Verify does is verify the solutions and makes sure they are correct.

The Digest::SHA Perl module implements the hash functions of the SHA family. It also provides the shasum binary.

This package provides a data pack for Business::ISBN. These data are generated from the RangeMessage.xml file provided by the ISBN Agency.

Config::Tiny is a Perl class to read and write .ini style configuration files with as little code as possible, reducing load time and memory overhead.

This module is primarily for reading human written files, and anything we write shouldn't need to have documentation/comments. If you need something with more power move up to Config::Simple, Config::General or one of the many other Config::* modules.

The Inline::C module allows you to write Perl subroutines in C. Since version 0.30 the Inline module supports multiple programming languages and each language has its own support module. This document describes how to use Inline with the C programming language. It also goes a bit into Perl C internals.

DateTime::Format::ISO8601 is a DateTime extension that parses almost all ISO8601 date and time formats.

CPAN::DistnameInfo uses heuristics to extract the distribution name and version from filenames.

This module provides a mechanism for determining if the pod for a given module is comprehensive.

Pod::Simple is a Perl library for parsing text in the Pod (plain old documentation) markup language that is typically used for writing documentation for Perl and for Perl modules.

This module provides basic Boolean support, by defining two special objects: true and false.

This module provides various type-testing functions. These are intended for functions that care what type of data they are operating on. There are two flavours of function. Functions of the first flavour provide type classification only. Functions of the second flavour also check that an argument is of an expected type. The type enforcement functions handle only the simplest requirements for arguments of the types handled by the classification functions. Enforcement of more complex types may be built using the classification functions, or it may be more convenient to use a module designed for the more complex job, such as Params::Validate

Set::IntSpan manages sets of integers. It is optimized for sets that have long runs of consecutive integers.

This library provides a set of Path::Tiny types and coercions for Specio. These types can be used with Moose, Moo, Params::ValidationCompiler, and other modules.

Encode module provides the interface between Perl strings and the rest of the system. Perl strings are sequences of characters.

This module provides an XS implementation for portions of Class::Load.

This module implements the algorithm for the solution of Bezier curves as presented by Robert D Miller in Graphics Gems V, "Quick and Simple Bezier Curve Drawing".

Devel::OverloadInfo returns information about overloaded operators for a given class (or object), including where in the inheritance hierarchy the overloads are declared and where the code implementing it is.

Statistics::Distributions calculates percentage points (5 significant digits) of the u (standard normal) distribution, the student's t distribution, the chi-square distribution and the F distribution. It can also calculate the upper probability (5 significant digits) of the u (standard normal), the chi-square, the t and the F distribution.

MIME-tools is a collection of Perl5 MIME:: modules for parsing, decoding, and generating single- or multipart (even nested multipart) MIME messages.

Magic is Perl's way of enhancing variables. This mechanism lets the user add extra data to any variable and hook syntactical operations (such as access, assignment or destruction) that can be applied to it. With this module, you can add your own magic to any variable without having to write a single line of XS.

This module handles parsing, modifying and creating configuration files of the style used by the Git version control system.

This package provides encodings for JIS X 0212, which is also known as JIS 2000.
