Hello all,

I nee some help to clarify the number operator. I thought that this would give me the number of photons, i.e. an integer. However, if i set shots =1 (to have samples) and compute the expectation value, i get non integers values.

For instance

```
dev = qml.device("strawberryfields.fock", wires=1, cutoff_dim=30,shots=1)
@qml.qnode(dev)
def quantum_neural_net(var):
qml.CoherentState(var[0],var[1],wires = 0)
return qml.expval(qml.NumberOperator(0))
```

i would expect samples according to the Poisson(3) distribution and indeed the expectation value is 3 but the individual samples are non integer, like below:

```
>>> print(quantum_neural_net([np.sqrt(3),0]))
1.596027833083245
```

How can i do to get integer when sampling (shots =1 )?

Thanks

Oriel
