How do you define a floating-point number in Python?

Solution

A floating-point number in Python is defined by including a decimal point in the number. Here's how you can define a floating-point number:

# Defining a floating-point number
my_float = 7.0
print(my_float)

# You can also define a floating-point number using scientific notation
my_float = 3.14e-10
print(my_float)

In the first example, 7.0 is a floating-point number. In the second example, 3.14e-10 is also a floating-point number. The e in 3.14e-10 stands for exponent, which means 3.14e-10 is equivalent to 3.14 * 10^-10.

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. Your code snippet should define the following function:
