A Number2 can be created,
- without parameter, equivalent to Number2(0, 0)
- with given x and y values

Returns a copy of the Number2.

local n1 = Number2(1, 0, 0)
local n2 = n1 -- n2 is not a copy but a direct reference to n1
n2.X = 10
print(n1.X) -- now n1.X == 10

-- using Copy:
local n1 = Number2(1, 0, 0)
local n2 = n1:Copy() -- n2 is a copy of n1, they're not the same Number2
n2.X = 10
print(n1.X) -- n1.X is still 1

Sets this Number2 to the linear interpolation between two given Number2 at a given ratio.

Normalizes the Number2 so that its magnitude becomes 1.0, and return it.

Sets this Number2's components to the given values, and return it.

Shortcut to unit vector Number2(0, -1).

This is a property of the global Number2, to be called as Number2.Down.

Same as Y property.

Shortcut to unit vector Number2(-1, 0).

This is a property of the global Number2, to be called as Number2.Left.

Magnitude of the Number2.

Shortcut to Number2(1, 1).

This is a property of the global Number2, to be called as Number2.One.

Shortcut to unit vector Number2(1, 0).

This is a property of the global Number2, to be called as Number2.Right.

Squared magnitude of the Number2.

Shortcut to unit vector Number2(0, 1).

This is a property of the global Number2, to be called as Number2.Up.

Same as X property.

X value of the Number2.

myNumber2.X = 42
print(myNumber2.X)

Y value of the Number2.

myNumber2.Y = 42
print(myNumber2.Y)

Shortcut to Number2(0, 0).

This is a property of the global Number2, to be called as Number2.Zero.
