Functions

Reference pages for every TrueCalc function, generated from the engine's functions.json registry.

The function registry (functions.json in truecalc/core at 57964975b79e7326c3b69ab21d53119171767e05) is not populated yet — function pages will appear here automatically once it is (tracked in truecalc/core#14).
