The correct method to round decimals in NumPy is np.around(). This function rounds an array to the given number of decimals. Here is a step by step guide on how to use it:

1. First, you need to import the NumPy library. You can do this by typing import numpy as np in your Python script.

2. Next, create a NumPy array or use an existing one. For example, you can create a new array like this: arr = np.array([1.23, 2.45, 3.67, 4.89]).

3. Now you can use the np.around() function to round the decimals. You need to pass the array and the number of decimals as arguments to the function. For example, if you want to round to 1 decimal place, you would type: rounded_arr = np.around(arr, 1).

4. If you print rounded_arr, you will see that all the numbers in the array have been rounded to 1 decimal place.

Note: np.fix() and np.trunc() are not rounding methods
