# Python Program explaining 
# compare_total_mag() method
  
# loading decimal library
from decimal import *
  
  
# Initializing a decimal value
a = Decimal(-1)
  
b = Decimal('0.142857')
  
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
  
  
# Using Decimal.compare_total_mag() method
print ("\n\nDecimal a with compare_total_mag() method : ", a.compare_total_mag(a))
  
print ("Decimal a with compare_total_mag() method : ", a.compare_total_mag(b))
  
print ("Decimal b with compare_total_mag() method : ", b.compare_total_mag(a))

Output :

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with compare_total_mag() method :  0
Decimal a with compare_total_mag() method :  1
Decimal b with compare_total_mag() method :  -1

Code #2 : Example for compare_total_mag() method




# Python Program explaining 
# compare_total_mag() method
  
# loading decimal library
from decimal import *
  
  
# Initializing a decimal value
a = Decimal('-3.14')
  
b = Decimal('321e + 5')
  
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
  
  
# Using Decimal.compare_total_mag() method
print ("\n\nDecimal a with compare_total_mag() method : ", a.compare_total_mag(a))
  
print ("Decimal a with compare_total_mag() method : ", a.compare_total_mag(b))
  
print ("Decimal b with compare_total_mag() method : ", b.compare_total_mag(a))

Output :

Decimal value a :  -3.14
Decimal value b :  3.21E+7


Decimal a with compare_total_mag() method :  0
Decimal a with compare_total_mag() method :  -1
Decimal b with compare_total_mag() method :  1
