Development Process

This translation is provided for information only. The German version is authoritative.

From idea to published calculator, every tool goes through a structured process.

Conception

Every calculator begins with professional research: What formula is it based on? Which official sources define the parameters? What are typical use cases?

Implementation

The calculation logic is implemented as a pure function without side effects. Test cases verify standard scenarios, boundary values, and known reference values. The interface follows the uniform platform design.

Quality assurance

The build runs backend and frontend tests, TypeScript type checking and size checks for delivered files. Browser tests cover navigation, language switching, result display and export, among other features.

Maintenance

Calculators with time-sensitive values are regularly reviewed. Changes to laws or official parameters are incorporated promptly.
