A turing-complete language for native Float4096 + Quaternary DNA + base4096 and some fun physics in there as well.
Before the great office remodel of 2025, I was fast at work over here -
Then when I was playing around with Javascript, I realized something - it’s easier to work with Java than to try to put lipstick on a pig. In this case, extremely large numbers are not native to Python. In fact, they’re not even that easy to pipeline in. So I did what anyone would do.. I created my own language in Java instead. This puts a pause on my python-based works, but hopefully after some sleep I can stand upon the shoulders of my old and faded-of-memory work and repurpose towards my Java-based language.

/**
* A high-precision floating-point number class with 4096-bit precision.
* Uses {@link BigDecimal} for underlying arithmetic with a fixed {@link MathContext}
* configured for 4096-bit precision and HALF_EVEN rounding.
* Provides arithmetic operations, comparisons, and utility methods for high-precision calculations.
*
* This library demonstrates functional completeness via subtraction, allowing simulation of arbitrary logic circuits
* (and thus supporting Turing-complete systems in principle). Boolean values are represented as +0.0 (true) and -0.0 (false).
* Logic gates are implemented using only subtraction, leveraging signed zeros.
*
* Additionally, supports deterministic generation of 4096 contrived and unique Unicode characters based on the value.
*
* Includes quaternary (base-4) DNA logic:
* - Quaternary logic gates (MIN, MAX, Inverter, Successor) for multi-valued logic.
* - DNA sequences as quaternary representations (A=0, C=1, G=2, T=3).
* - Safe math operations on DNA sequences (element-wise gates, addition in base-4).
* - Base-4096 encoding/decoding using DNA sequences, where 6 DNA bases encode one base-4096 symbol (since 4^6 = 4096).
* - Uses a fixed alphabet of 4096 unique characters for base-4096 symbols.
*
* To ensure full Turing completeness, includes a DNA-based Turing Machine simulator.
* The Turing Machine uses DNA sequences for the tape (quaternary symbols), quaternary logic for transitions,
* and safe BigDecimal/BigInteger operations where needed to avoid overflows.
* Supports all standard Turing operations: read/write, move left/right, state transitions, halting.
* Can simulate any Turing-computable function, demonstrating the library's Turing completeness elegantly.

/**
* A high-precision floating-point number class with 4096-bit precision.
* Uses {@link BigDecimal} for underlying arithmetic with a fixed {@link MathContext}
* configured for 4096-bit precision and HALF_EVEN rounding.
* Provides arithmetic operations, comparisons, and utility methods for high-precision calculations.
*
* This library demonstrates functional completeness via subtraction, allowing simulation of arbitrary logic circuits
* (and thus supporting Turing-complete systems in principle). Boolean values are represented as +0.0 (true) and -0.0 (false).
* Logic gates are implemented using only subtraction, leveraging signed zeros.
*
* Additionally, supports deterministic generation of 4096 contrived and unique Unicode characters based on the value.
*
* Includes quaternary (base-4) DNA logic:
* - Quaternary logic gates (MIN, MAX, Inverter, Successor) for multi-valued logic.
* - DNA sequences as quaternary representations (A=0, C=1, G=2, T=3).
* - Safe math operations on DNA sequences (element-wise gates, addition in base-4).
* - Base-4096 encoding/decoding using DNA sequences, where 6 DNA bases encode one base-4096 symbol (since 4^6 = 4096).
* - Uses a fixed alphabet of 4096 unique characters for base-4096 symbols.
*
* To ensure full Turing completeness, includes a DNA-based Turing Machine simulator.
* The Turing Machine uses DNA sequences for the tape (quaternary symbols), quaternary logic for transitions,
* and safe BigDecimal/BigInteger operations where needed to avoid overflows.
* Supports all standard Turing operations: read/write, move left/right, state transitions, halting.
* Can simulate any Turing-computable function, demonstrating the library's Turing completeness elegantly.

/**
* A high-precision floating-point number class with 4096-bit precision.
* Uses {@link BigDecimal} for underlying arithmetic with a fixed {@link MathContext}
* configured for 4096-bit precision and HALF_EVEN rounding.
* Provides arithmetic operations, comparisons, and utility methods for high-precision calculations.
*
* This library demonstrates functional completeness via subtraction, allowing simulation of arbitrary logic circuits
* (and thus supporting Turing-complete systems in principle). Boolean values are represented as +0.0 (true) and -0.0 (false).
* Logic gates are implemented using only subtraction, leveraging signed zeros.
*
* Additionally, supports deterministic generation of 4096 contrived and unique Unicode characters based on the value.
*
* Includes quaternary (base-4) DNA logic:
* - Quaternary logic gates (MIN, MAX, Inverter, Successor) for multi-valued logic.
* - DNA sequences as quaternary representations (A=0, C=1, G=2, T=3).
* - Safe math operations on DNA sequences (element-wise gates, addition in base-4).
* - Base-4096 encoding/decoding using DNA sequences, where 6 DNA bases encode one base-4096 symbol (since 4^6 = 4096).
* - Uses a fixed alphabet of 4096 unique characters for base-4096 symbols.
*
* To ensure full Turing completeness, includes a DNA-based Turing Machine simulator.
* The Turing Machine uses DNA sequences for the tape (quaternary symbols), quaternary logic for transitions,
* and safe BigDecimal/BigInteger operations where needed to avoid overflows.
* Supports all standard Turing operations: read/write, move left/right, state transitions, halting.
* Can simulate any Turing-computable function, demonstrating the library's Turing completeness elegantly.
*
* Creates its own native language: QuatDnaLang, a quaternary Brainfuck variant optimized for DNA and the library.
* Programs are DNA strings, parsed in pairs for commands, executed on a quaternary tape using the library's logic gates.
* This language is Turing-complete, self-contained, and leverages the library's quaternary DNA features for elegance.
* Supports recursive evaluation via 'TT' command, allowing programs to execute sub-programs from the tape, vertically integrating the language with itself.
*
* Integrates recursive dimensional DNA framework for computing physical constants elegantly.
* Uses high-precision exponentiation and logarithms for fractional powers in the formulas.
* Constants are computed recursively using the golden ratio structure, vertically integrating math, logic, and language.

/**
* A high-precision floating-point number class with 4096-bit precision, rooted in the golden ratio (φ).
* Uses {@link BigDecimal} for arithmetic with a fixed {@link MathContext} for 4096-bit precision and HALF_EVEN rounding.
* Provides arithmetic, logic, and a native Turing-complete language (QuatDnaLang) for recursive computation.
* Integrates a recursive dimensional framework to compute physical constants using φ-based scaling.
*
* Functional completeness is achieved via subtraction-based logic gates (+0.0 = true, -0.0 = false).
* Quaternary DNA logic (A=0, C=1, G=2, T=3) supports base-4096 encoding (4^6 = 4096) and Turing machine simulation.
* QuatDnaLang is a minimal, recursive language using DNA pairs, optimized for self-similar computation.
* Physical constants (e.g., Planck’s constant, gravitational constant) are computed via a unified recursive formula.
* Prime numbers are estimated using an entropy-aware recursive index, harmonizing with φ-based structures.
*
* The library is vertically integrated: arithmetic, logic, language, and constants are unified under φ-based recursion.
* QuatDnaLang can now compute constants/primes via the 'GG' command, completing the integration.

/**
* High-precision floating-point class with 4096-bit precision, rooted in the golden ratio (φ).
* Provides arithmetic, quaternary DNA logic, and a Turing-complete language (QuatDnaLang).
* Integrates a recursive dimensional framework for physical constants and prime estimation.
* Vertically integrated: arithmetic, logic, language, and constants are unified under φ-based recursion.
* Optimized for elegance with sparse tape, concise logic, and consolidated constant computation.
