python - strange behavior of scipy.stats.rankdata

Is there an explanation of the following output?

In [1]: import scipy.stats as ss
In [2]: ss.rankdata([1, 2, 3, 3, 4, 3, 4, 5])
Out [2]: array([1. , 2. , 4. , 4. , 6.5, 4. , 6.5, 8. ])

I was expected the following output, without decimals for the rankings.

Out [2]: array([1. , 2. , 4. , 4. , 6., 4. , 6., 8. ])

Also, why are the rankings of type float instead of type int?

As per the SciPy webpage here, the default method is 'average' which returns the average of the ranks. Try other options of method.
