Linearly interpolates between two values by a normalized value. Linearly interpolates between two values by a normalized value. This is the opposite of [method inverse_lerp].
If the [code]from[/code] and [code]to[/code] arguments are of type [int] or [float], the return value is a [float]. 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).

Linearly interpolates between two angles (in radians) by a normalized value. Linearly interpolates between two angles (in radians) by a normalized value.
Similar to [method lerp] but interpolate correctly when the angles wrap around [constant @GDScript.TAU]. Similar to [method lerp], but interpolates correctly when the angles wrap around [constant @GDScript.TAU].
