.. _class_int:

int
===

Integer built-in type.

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.


.. tabs::

 .. code-tab:: gdscript

    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.

 .. code-tab:: csharp

    int myInt = (int)"6.7".ToFloat(); // int, value 6, the String is explicitly cast with int.
    // We have to use `long` here, because GDSript's `int`
    // is 64 bits long while C#'s `int` is only 32 bits.
    long maxInt = 9223372036854775807;
    GD.Print(maxInt); // 9223372036854775807, OK.
    maxInt++;
    GD.Print(maxInt); // -9223372036854775808, we overflowed and wrapped around.
    
    // Alternatively, if we used C#'s 32-bit `int` type, the maximum value is much smaller:
    int halfInt = 2147483647;
    GD.Print(halfInt); // 2147483647, OK.
    halfInt++;
    GD.Print(halfInt); // -2147483648, we overflowed and wrapped around.

Constructor Descriptions
------------------------

.. _class_int_constructor_int:

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

Constructs a default-initialized ``int`` set to ``0``.

----

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

Constructs an ``int`` as a copy of the given ``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 (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.

Operator Descriptions
---------------------

.. _class_int_operator_neq_bool:

- :ref:`bool<class_bool>` **operator !=** **(** :ref:`float<class_float>` right **)**

Returns ``true`` if this ``int`` is not equivalent to the given :ref:`float<class_float>`.

----

- :ref:`bool<class_bool>` **operator !=** **(** :ref:`int<class_int>` right **)**

----

.. _class_int_operator_mod_int:

- :ref:`int<class_int>` **operator %** **(** :ref:`int<class_int>` right **)**

Returns the remainder after dividing two integers. This operation uses truncated division, which is often not desired as it does not work well with negative numbers. Consider using :ref:`@GlobalScope.posmod<class_@GlobalScope_method_posmod>` instead if you want to handle negative numbers.
