GridCalc

The application functions as a structured RPN (Reverse Polish Notation) calculator and spreadsheet designed to enable transparent, visual, and editable computational workflows. Its main features include a cell-based execution grid where each calculation step is visible and modifiable, support for precise arithmetic using constructive real numbers to eliminate floating-point errors, reference reusability for building modular and repeatable models, and an intuitive interface that allows for instant recalculations after any input or edit. It addresses the need for accurate, fast, and transparent modeling and data analysis by engineers, scientists, and professionals who require deterministic results, detailed inspection of calculations, and flexibility in handling complex mathematical operations without hidden processes or ambiguous formulas.

GridCalc can be found in No-Code Database & Spreadsheet Apps categories.
