Most utility classes are final with static methods and cannot be instantiated directly. `Console` is the exception — a singleton with instance methods and internal style state, accessed via `Console::getInstance()`. --- Development and Quality Assurance --------------------------------- [](#development-and-quality-assurance) [Claude Chat](https://claude.ai) and [Claude Code](https://www.claude.com/product/claude-code) were used in the development of this package. The core classes were designed, coded, and commented primarily by the author, with Claude providing substantial assistance with code review, suggesting improvements, debugging, and generating tests and documentation. All code was thoroughly reviewed by the author, and validated using industry-standard tools including [PHP\_Codesniffer](https://github.com/PHPCSStandards/PHP_CodeSniffer/), [PHPStan](https://phpstan.org/) (to level 9), and [PHPUnit](https://phpunit.de/index.html) to ensure full compliance with [PSR-12](https://www.php-fig.org/psr/psr-12/)coding standards and comprehensive unit testing with 100% code coverage. This collaborative approach has produced a well-designed, production-ready package with thorough test coverage and documentation.

This class serves as the basis of the `Console::dump()` method. ### [Environment](docs/Environment.md) [](#environment) Runtime environment detection: 64-bit architecture checks, and locale detection from the HTTP `Accept-Language` header. ### [Console](docs/Console.md) [](#console) Singleton for ANSI/SGR-styled console output: 16-color foreground/background, text attributes (bold, italic, underline, etc.), method chaining, style snapshot/restore, and higher-level helpers like `dump()` and severity-colored messages (`success()`, `error()`, `warn()`, `info()`). --- [Globals](docs/Globals.md) -------------------------- [](#globals) Useful constants (`M_TAU`, `RECURSION`) that work better as globals (namespaced to `OceanMoon\Core`) than as class members. --- Traits ------ [](#traits) ### Comparison Traits [](#comparison-traits) Equality and ordering comparison operations for custom types. See [ComparisonTraits.md](docs/Traits/Comparison/ComparisonTraits.md) for the trait hierarchy and usage guide. TraitDescription[Equatable](docs/Traits/Comparison/Equatable.md)Base trait for exact equality comparison via `equal()`.[Comparable](docs/Traits/Comparison/Comparable.md)Extends Equatable with ordering: `lessThan()`, `greaterThan()`, etc.[ApproxEquatable](docs/Traits/Comparison/ApproxEquatable.md)Extends Equatable with tolerance-based `approxEqual()`.[ApproxComparable](docs/Traits/Comparison/ApproxComparable.md)Combines Comparable and ApproxEquatable with `approxCompare()`.### Assert Traits [](#assert-traits) Custom PHPUnit assertions for test cases. See [TestingTraits.md](docs/Traits/Asserts/TestingTraits.md) for usage examples. TraitDescription[FloatAssertions](docs/Traits/Asserts/FloatAssertions.md)Provides `assertApproxEqual()` with informative failure messages.--- Enums ----- [](#enums) ### [FloatFormat](docs/Enums/FloatFormat.md) [](#floatformat) Notation styles for `Floats::format()` — fixed-point, scientific, or automatic selection between the two. ### [ExponentFormat](docs/Enums/ExponentFormat.md) [](#exponentformat) Rendering styles for the exponent portion of scientific-notation float output, from plain ASCII `e`/`E` through to Unicode and HTML mathematical notation. --- Exceptions ---------- [](#exceptions) ### [FormatException](docs/Exceptions/FormatException.md) [](#formatexception) Exception thrown when a string has an invalid format for the desired operation. Extends `DomainException`. Useful for parse methods or constructors that accept string arguments. ### [ArithmeticException](docs/Exceptions/ArithmeticException.md) [](#arithmeticexception) Exception thrown when an arithmetic operation has no defined result for the given operands, such as division by zero or a logarithm of a non-positive number. Extends `DomainException`. Displaces `DivisionByZeroError` for userland arithmetic code in value types like `Complex`, `Rational`, `Vector`, and `Matrix`. --- Testing ------- [](#testing) The library includes comprehensive test coverage: ``` # Run all tests vendor/bin/phpunit # Run specific test class vendor/bin/phpunit tests/NumbersTest.php # Run with coverage (generates HTML report and clover.xml) composer test ``` --- License ------- [](#license) MIT License - see [LICENSE](LICENSE) for details --- Support ------- [](#support) - **Issues**: - **Documentation**: See [docs/](docs/) directory for detailed class documentation - **Examples**: See test files for comprehensive usage examples For questions or suggestions, please [open an issue](https://github.com/mossy2100/PHP-Core/issues). --- Changelog --------- [](#changelog) See [CHANGELOG.md](CHANGELOG.md) for version history and changes. ### Health Score 44 — FairBetter than 90% of packages Maintenance89 Actively maintained with recent releases Popularity6 Limited adoption so far Community14 Small or concentrated contributor base Maturity60 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
