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 [method 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:

- :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.

----

- :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, so for example ``int(2.7)`` will be equals to 2, ``int(.1)`` will be equals to 0 and ``int(-2.7)`` will be equals to -2.

----

- :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.
