> Project: Flink
> Issue Type: Bug
> Components: API / Python
> Affects Versions: 1.11.0, 1.12.0

> When you use floats are index of pandas, it produces a wrong results:
>
> {code:java}
> >>> import pandas as pd
> >>> t_env.from_pandas(pd.DataFrame({'a': [1, 2, 3]}, index=[2., 3.,
> >>> 4.])).to_pandas()
> a
> 0 1
> 1 2
> {code}
>
> This is because direct slicing uses the value as index when the index
> contains floats:
>
> {code:java}
> >>> pd.DataFrame({'a': [1,2,3]}, index=[2., 3., 4.])[2:]
> a
> 2.0 1
> 3.0 2
> 4.0 3
> >>> pd.DataFrame({'a': [1,2,3]}, index=[2., 3., 4.]).iloc[2:]
> a
> 4.0 3
> >>> pd.DataFrame({'a': [1,2,3]}, index=[2, 3, 4])[2:]
> a
> 4 3{code}
