What is the numpy.floor() function in NumPy?
The numpy.floor() function in NumPy is used to return the floor values of each element in an input array x such that for each of the elements of x, the floor values are less than or equal to it.

I am edit answer with @DanielF explanation: "floor doesn't convert to integer, it just gives integer-valued floats, so you still need an astype to change to int" Check this code to understand the solution:
import numpy as np
arr = np.random.rand(1, 10) * 10
print(arr)
arr = np.floor(arr).astype(int)
print(arr)
OUTPUT:
[[2.76753828 8.84095843 2.5537759 5.65017407 7.77493733 6.47403036
7.72582766 5.03525625 9.75819442 9.10578944]]
[[2 8 2 5 7 6 7 5 9 9]]

As alternative to changing type after floor division, you can provide an output array of the desired data type to np.floor (and to any other numpy ufunc). For example, imagine you want to convert the output to np.int32, then do the following:
import numpy as np
arr = np.random.rand(1, 10) * 10
out = np.empty_like(arr, dtype=np.int32)
np.floor(arr, out=out, casting='unsafe')
As the casting argument already indicates, you should know what you are doing when casting outputs into different types. However, in your case it is not really unsafe.
Although, I would not call np.floor in your case, because all values are greater than zero. Therefore, the simplest and probably fastest solution to your problem would be a direct casting to integer.
import numpy as np
arr = (np.random.rand(1, 10) * 10).astype(int)
