About
About Protocol5
Protocol5 began as a public mathematical experiment and now serves as the front door for exact arithmetic, radix conversion, and sequence references.
Technology
Then and now
The original site referenced Microsoft Azure, C#, and TypeScript. The current version keeps the math-provider core, adds stronger testing, and separates static editorial pages from the interactive calculator app.
Intent
A public home for number work
Protocol5 exists to make exact arithmetic, radix conversion, sequence exploration, and transparent text math understandable instead of opaque.
