Linearly interpolates between two values by a normalized value.
If the [code]from[/code] and [code]to[/code] arguments are of type [int] or [float], the return value is a [float].
If both are of the same vector type ([Vector2], [Vector3] or [Color]), the return value will be of the same type ([code]lerp[/code] then calls the vector type's [code]linear_interpolate[/code] method).
[codeblock]
lerp(1, 3, 0.5) # returns 2
lerp(0, 4, 0.75) # returns 3.0
lerp(Vector2(1, 5), Vector2(3, 2), 0.5) # returns Vector2(2, 3.5)
