-				Returns a normalized value considering the given range. This is the opposite of [method lerp].
+				Returns an interpolation or extrapolation factor considering the range specified in [code]from[/code] and [code]to[/code], and the interpolated value specified in [code]weight[/code]. The returned value will be between [code]0.0[/code] and [code]1.0[/code] if [code]weight[/code] is between [code]from[/code] and [code]to[/code] (inclusive). If [code]weight[/code] is located outside this range, then an extrapolation factor will be returned (return value lower than [code]0.0[/code] or greater than [code]1.0[/code]).
