(Optionally) Integrate the plugin into your workflows

States: read the live entry line, the result as formatted text and as a Bubble number, Ans, the memory value, the angle mode, the Shift state, an error flag, an error message and code, and the full calculation history as a list or as JSON.

Events: start a workflow when a calculation completes, when one produces an error, when the calculator is cleared, when memory changes, or when the angle mode changes.

Actions: connect the calculator to your buttons or logic: Set Expression, Append to Expression, Clear, Evaluate, Set Angle Mode, and Clear History.

Physical keyboard: when focused, the calculator accepts digits, operators, parentheses, Enter to evaluate, Backspace to delete, and Escape to clear, without capturing keys from the rest of your page.

Documentation and AI support

We built the documentation we wish every plugin had.
A full user guide covers every field, every state, every workflow recipe, and a complete troubleshooting section.

Plus, the plugin ships with a context document designed to be pasted into any LLM. Once pasted, your AI assistant knows every field, every state, every event, every strategy, and the most common configuration patterns of the plugin. It can write your Bubble dynamic expressions and suggest the right configuration for your specific use case, without you having to dig through documentation yourself.
You can download it from the user documentation.
