We advise against using this. It may be changed or removed in a future update. You should use Entity:SetNWFloat instead.
Sets a networked float value at specified index on the entity.
The value then can be accessed with Entity:GetNetworkedFloat both from client and server.
Seems to be the same as Entity:GetNetworkedInt.
Running this function clientside will only set it clientside for the client it is called on.
