Python | Decimal canonical() method

Last Updated : 05 Sep, 2019

Decimal#canonical() : canonical() is a Decimal class method which returns the canonical encoding of the Decimal value.

Syntax: Decimal.canonical()
Parameter: Decimal values
Return: the canonical encoding of the Decimal value.

Code #1 : Example for canonical() method

# Python Program explaining 
# canonical() 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.canonical() method
print ("\n\nDecimal a with canonical() method : ", a.canonical())
  
print ("Decimal b with canonical() method : ", b.canonical())

Output :

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with canonical() method :  -1
Decimal b with canonical() method :  0.142857

Code #2 : Example for canonical() method

# Python Program explaining 
# canonical() 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.canonical() method
print ("\n\nDecimal a with canonical() method : ", a.canonical())
  
print ("Decimal b with canonical() method : ", b.canonical())

Output :

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


Decimal a with canonical() method :  -3.14
Decimal b with canonical() method :  3.21E+7
