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 of the 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
