Solution

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

import numpy as np def convert_to_fixed(floating_point): # convert floating_point to fixed-point format # return fixed_point as a string of the binary representation of this converted number fin_int = int(floating_point*2**5) b = bin(fin_int) fixed_point = '' i = len(b) - 2 if fin_int > 0: fixed_point += '0' else: fixed_point += '1' while i < 8: fixed_point += '0' i += 1 for i in range(2, len(b)): fixed_point += b[i] return fixed_point print(convert_to_fixed(3.013)) and you want to store this number using the format. This will require bits. The process to convert a floating-point number into a fixed-point number can be described by the following steps: Multiply the float by : Round the result to the nearest integer. Your result should be . Convert this integer to binary representation, where the binary representation is stored as a string. You can use the bin() function. Just be aware that the format returned by bin() is not exactly the binary representation. For example, bin(24) = '0b11000' and bin(-24) = '-0b11000', but the binary representation of the number 24 is '11000'. If this string has less than bits, then pad the left with zeros: '11000' -> '00011000'. Else, store the right-most bits. Add the sign bit ('0' or '1') to the binary number on the left: '00011000'->'000011000' Task: Write a function that takes a floating-point number, converts it to fixed-point and returns a string containing the 9-bit binary representation of the fixed-point number in Q(3.5) format.
