# Point2DSignal

`abs`

`abs(): ScalarSignal`

`normalize`

`normalize(v: VectorSignal): VectorSignal normalize(): VectorSignal`

Returns the normalized (unit) vector in the direction of the original vector as a

`VectorSignal`

.`pow`

`pow(exponent: ScalarSignal): ScalarSignal`

Returns a signal with the value that is the base signal raised to the power of the exponent signal. The result is undefined if the base is negative, or if the base is zero and the exponent is not positive.

`ReactiveModule.pow`

`reflect`

`reflect(incident: VectorSignal, normal: VectorSignal): VectorSignal reflect(normal: VectorSignal): VectorSignal`

Calculates the reflection direction for an incident vector and a normal as a

`VectorSignal`

.`round`

`round(): ScalarSignal`

Returns a signal with the value that is the rounded value of the given signal.

**Note**: When the fractional part is 0.5, it rounds the number away from zero, which is at odds with JavaScript standard behavior of rounding it always up in such cases. Therefore, this function is NOT exactly the reactive counterpart of the standard JavaScript
