int
===

Integer built-in type.

.. rst-class:: classref-introduction-group

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

Signed 64-bit integer type.

It can take values in the interval ``[-2^63, 2^63 - 1]``, i.e. ``[-9223372036854775808, 9223372036854775807]``. Exceeding those bounds will wrap around.

\ **int** is a :ref:`Variant<class_Variant>` type, and will thus be used when assigning an integer value to a :ref:`Variant<class_Variant>`. It can also be enforced with the ``: int`` type hint.

::

    var my_variant = 0 # int, value 0.
    my_variant += 4.2 # float, value 4.2.
    var my_int: int = 1 # int, value 1.
    my_int = 4.2 # int, value 4, the right value is implicitly cast to int.
    my_int = int("6.7") # int, value 6, the String is explicitly cast with int.
    
    var max_int = 9223372036854775807
    print(max_int) # 9223372036854775807, OK.
    max_int += 1
    print(max_int) # -9223372036854775808, we overflowed and wrapped around.

Method Descriptions
-------------------

.. _class_int_method_int:

.. rst-class:: classref-method

:ref:`int<class_int>` **int** **(** :ref:`bool<class_bool>` from **)**

Cast a :ref:`bool<class_bool>` value to an integer value, ``int(true)`` will be equals to 1 and ``int(false)`` will be equals to 0.

.. rst-class:: classref-item-separator

----

.. rst-class:: classref-method

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

Cast a float value to an integer value, this method simply removes the number fractions (i.e. rounds ``from`` towards zero), so for example ``int(2.7)`` will be equals to 2, ``int(0.1)`` will be equals to 0 and ``int(-2.7)`` will be equals to -2. This operation is also called truncation.

.. rst-class:: classref-item-separator

----

.. rst-class:: classref-method

:ref:`int<class_int>` **int** **(** :ref:`String<class_String>` from **)**

Cast a :ref:`String<class_String>` value to an integer value, this method is an integer parser from a string, so calling this method with an invalid integer string will return 0, a valid string will be something like ``'1.7'``. This method will ignore all non-number characters, so calling ``int('1e3')`` will return 13.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
