# Nearest Multiple Spike
Nearest Multiple Spikes will move the motor in either direction to the **closest multiple** of **Factor** plus **Offset.** Put in other words:
$$
NewTargetPosition=NearestMultiple(Factor+offSet)
$$
The $$NearestMultiple(Factor+offSet)$$is found by calculating the $$New Forward Position$$ and the $$New Reverse Position$$, then selecting which one is closest to the $$Current Motor Position$$ and setting that as the New Target Position.
#### For Math Nerds
* $$P\_C=$$ Current Position
* $$R↑=$$ Round Up
* $$R↓=$$ Round Down
* $$F=$$ Factor Value
* $$S=$$ Offset Value
$$
|P\_C-(R↑\[P\_C/F]\*F+S)| <^? |P\_C-(R↓\[P\_C/F]\*F+S)|
$$
#### If Yes, $$NewTargetPosition=NewForwardPosition$$
$$
New Forward Position = Round↑(CurrentMotorPosition/Factor) \* Factor + Offset
$$
#### If No, $$NewTargetPosition=NewReversePosition$$
$$
New Reverse Position = Round↓(CurrentMotorPosition/Factor) \* Factor + Offset
$$
### Changing the Type
Nearest multiple spikes are denoted with a `↔` (left right arrow) and use a **Factor** and an **Offset.**
To change the type double click in the **Type** column and select **Nearest Multiple** then press `enter` or `tab` to save it.
### Changing the Factor
To change the factor double click in the **Factor** column give it a new factor and then press `enter` or `tab` to save it.
### Changing the Offset
To change the offset double click in the **Offset** column give it a new offset and then press `enter` or `tab` to save it.
