CalcTree supports a wide range of mathematical functions using the MathJS expression engine. Most functions behave exactly as they do in MathJS, but some have CalcTree-specific behaviors—especially with units, parameter referencing, and data types.

Functions are grouped by category. Click a category below to view syntax, examples, and any CalcTree-specific notes.
