CalcMD is an open specification that extends markdown tables with embedded formulas, making AI-generated calculations transparent, checkable, and Git-friendly.
Formulas use human-readable column names (like Total=Qty*Price) instead of cell references. They degrade gracefully in any standard markdown viewer and diff cleanly in Git.
Total=Qty*Price
Supported features: arithmetic, comparisons, logical operators, aggregations (sum, avg, min, max, count), math functions (round, abs, floor, ceil), and conditionals (if).
