代碼1:canonical()方法示例

# 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())

輸出:

Decimal value a :  -1
Decimal value b :  0.142857


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

代碼2:canonical()方法的示例

# 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())

輸出:

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
