## Scripting Rules


2 


3 
For scripts, there are some basic but important development rules that all scripts need to follow to ensure the scripts are compatible across multiple systems.

5 
For behavior in your script that affects actual gameplay, there are restrictions of what you can do with numbers. These are the rules:


6 


7 
* Only integer numbers are allowed; floatingpoint numbers are forbidden


8 
* If you divide, divide by powers of 2 if you can


9 
* If you want to divide by a different integer value, use the `div` function for integer division


10 
* Keep your numbers within (+/) 2<sup>53</sup>


11 
* Avoid `math.floor` and `math.ceil`

These restrictions on numbers don't apply to numbers that you don't use for gameplay but for stuff like harmless eye candy.

Failing to follow these rules might lead your script to behave differently on different systems, leading to desynchronization bugs, which means they will not work online.
