Python Math: Print the floating point from mantissa, exponent pair

Python Math: Exercise-58 with Solution

Write a Python program to print the floating point from mantissa, exponent pair.

Sample Solution:-

Python Code:

import math

print('{:^7}  {:^8}  {:^17}'.format('Mantissa', 'Exponent', 'Floating point value'))
print('{:-^8}  {:-^8}  {:-^20}'.format('', '', ''))

for m, e in [ (0.7, -3),
              (0.3,  0),
              (0.5,  3),
              ]:
    x = math.ldexp(m, e)
    print('{:7.2f}  {:7d}  {:7.2f}'.format(m, e, x))
	

Sample Output:

Mantissa  Exponent  Floating point value                                                                      
--------  --------  --------------------                                                                      
   0.70       -3     0.09                                                                                     
   0.30        0     0.30                                                                                     
   0.50        3     4.00

Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

str="+++Welcome python+++"
str.strip()

print(str)

Output:

+++Welcome python+++
