[0.15.9] Train stop not outputing fluid if it's too low

[Neemys]

1 train with a tank wagon with any fluid inside (here water), very low amount inside (here 0.6 water per tank, so 1.8 for the whole wagon).

When hovering the train, it tell us that there is 1.8 amount of water inside.

The train stop at a stop that is set to output it's content into the circuit network.

Actual behavior : The train do not output anything into the circuit network (see in the image below that there is no signal when I hover the pole connected to the stop).

Expected behavior : The train output 1.8 (or a rounded up value) into the circuit network.

As a side note : The train still consider itself NOT empty even if it output nothing into the circuit network.

I was able to get those low amount by using a pump activated by the signal sended by the train, obviously, when the signal stopped (too early as there is still water inside) the pump stopped leaving the water in the train.

The setup in your save does not allow for pump connection, changing that fixes it.

I'm not complaining about pump not working here (and it work, see how the pump is connected on the first screenshot), and if I remove the circuit network condition, the pump do remove what is inside the train. My report is about the train not sending it's content to the circuit network even if it is not empty (but the content is very low).

The save I gave is only here to show the train with content that do not what it should.

The circuit network handles integers, 0.6 means it contains 0, that is intentional.

[Neemys]

the train has 1.8 total, should output 1 or 2 depending on the rounding no ?

Or the problem is that the circuit network receive 3 signal of 0.6 and round each one before adding them ? So even if the network receive 1000 time a 0.6 signal it will still show 0 ?
