i was confused with qcut function
I was confused with **qcut** after runing the following codes:
```python
s = pd.Series(range(19))
qc = pd.qcut(s,
            q=[0., .1, .3, .7, .9, 1.],
            labels=[.8, .9, 1., 1.1, 1.2])
qc.to_numpy()
```
#### Problem description
after running above codes, I get the result.( **please note, there is two 1.2, seven 1.**)
```python
array([0.8, 0.8, 0.9, 0.9, 0.9, 0.9, 1. , 1. , 1. , 1. , 1. , 1. , 1. , 1.1, 1.1, 1.1, 1.1, 1.2, 1.2])
```

As my supposed, the results should be:( **one 1.2, eight 1.**)
```python
array([0.8, 0.8, 0.9, 0.9, 0.9, 0.9, 1., 1. , 1. , 1. , 1. , 1. , 1. , 1. , 1.1, 1.1, 1.1, 1.1, 1.2])
```
so, could you please help me to get the expected result?
