WebThe N-dimensional array ( ndarray) # An ndarray is a (usually fixed-size) multidimensional container of items of the same type and size. The number of dimensions and items in an array is defined by its shape , which is a tuple of N non-negative integers that specify the sizes of each dimension. Web2 mrt. 2024 · You can easily achieve this by declaring the data type in .to_numpy: num_arr = num_df.to_numpy (dtype = 'int') In this code, the dtype argument is set to "int" (short for integer). Printing the new num_arr variable to the terminal confirms the array only contains integers: You can see that NumPy does not perform any rounding.
