Description
-----------

Real Array. Array of floating point values. Can only contain floats. Optimized for memory usage, can't fragment the memory.

Member Function Description
---------------------------

.. _class_RealArray_RealArray:

- :ref:`RealArray<class_realarray>`  **RealArray**  **(** :ref:`Array<class_array>` from  **)**

Create from a generic array.

.. _class_RealArray_push_back:

- void  **push_back**  **(** :ref:`float<class_float>` value  **)**

Append an element at the end of the array.

.. _class_RealArray_resize:

- void  **resize**  **(** :ref:`int<class_int>` idx  **)**

Set the size of the :ref:`RealArray<class_realarray>`. If larger than the current size it will reserve some space beforehand, and if it is smaller it will cut off the array.

.. _class_RealArray_set:

- void  **set**  **(** :ref:`int<class_int>` idx, :ref:`float<class_float>` value  **)**

Change the float at the given index.

.. _class_RealArray_size:

- :ref:`int<class_int>`  **size**  **(** **)**

Return the size of the array.
