Method Descriptions

.. _class_float_method_float:

- :ref:`float<class_float>` **float** **(** :ref:`bool<class_bool>` from **)**

Cast a :ref:`bool<class_bool>` value to a floating point value, ``float(true)`` will be equal to 1.0 and ``float(false)`` will be equal to 0.0.

----

- :ref:`float<class_float>` **float** **(** :ref:`int<class_int>` from **)**

Cast an :ref:`int<class_int>` value to a floating point value, ``float(1)`` will be equal to 1.0.

----

- :ref:`float<class_float>` **float** **(** :ref:`String<class_String>` from **)**

Cast a :ref:`String<class_String>` value to a floating point value. This method accepts float value strings like ``"1.23"`` and exponential notation strings for its parameter so calling ``float("1e3")`` will return 1000.0 and calling ``float("1e-3")`` will return 0.001.
