<brief_description>
Vector used for 3D math using integer coordinates.
</brief_description>
<description>
3-element structure that can be used to represent positions in 3D space or any other pair of numeric values.
It uses integer coordinates and is therefore preferable to [Vector3] when exact precision is required.
[b]Note:[/b] In a boolean context, a Vector3i will evaluate to [code]false[/code] if it's equal to [code]Vector3i(0, 0, 0)[/code]. Otherwise, a Vector3i will always evaluate to [code]true[/code].

<argument index="0" name="from" type="Vector3">
</argument>
<description>
Constructs a new [Vector3i] from [Vector3]. The floating point coordinates will be truncated.
</description>
</method>
<method name="max_axis">
<return type="int">
</return>
<description>
Returns the axis of the vector's largest value. See [code]AXIS_*[/code] constants. If all components are equal, this method returns [constant AXIS_X].
</description>
</method>
<method name="min_axis">
<return type="int">
</return>
<description>
Returns the axis of the vector's smallest value. See [code]AXIS_*[/code] constants. If all components are equal, this method returns [constant AXIS_Z].
</description>
</method>
<method name="sign">
<return type="Vector3i">
</return>
<description>
Returns the vector with each component set to one or negative one, depending on the signs of the components.
