44. Fraction from Float Conversion

Write a Python program to create fraction instances of float numbers.

Sample Solution:

Python Code:

import fractions
for n in [0.2, 0.7, 6.5, 6.0]:
    print('{} = {}'.format(n, fractions.Fraction(n)))
	

Sample Output:

0.2 = 3602879701896397/18014398509481984                                                                      
                                                                                                              
0.7 = 3152519739159347/4503599627370496                                                                       
                                                                                                              
6.5 = 13/2                                                                                                    
                                                                                                              
6.0 = 6

• Write a Python script to generate random floats, convert each to a Fraction, and then display the fractions in a list.
• Write a Python function that takes a float as input, converts it to a Fraction, and then simplifies the fraction before printing it.
• Write a Python program to compare the Fraction obtained from a float with that from a string representation of the same number and print both.
