Built-in Constants
=======================

FuncSketch provides the following built-in constants
that can be used in function expressions:

Mathematical Constants
----------------------------

.. csv-table::
    :header: "Constant", "Type", "Value", "Description"

    "``pi``", "Real", "3.14159...", "Pi (:math:`\pi`)"
    "``e``", "Real", "2.71828...", "Euler's number or Napier's constant (:math:`e`)"

.. note::
    Future implementation will support additional built-in constants
    including physical constants.
