Python | Decimal as_integer_ratio() method

Last Updated : 05 Sep, 2019

Decimal#as_integer_ratio() : as_integer_ratio() is a Decimal class method which returns the exponent after shifting out the coefficient’s rightmost digits until only the lead digit remains : as a pair (n, d)

Syntax: Decimal.as_integer_ratio()
Parameter: Decimal values
Return: the exponent after shifting out the coefficient’s rightmost digits until only the lead digit remains : as a pair (n, d)

Code #1 : Example for as_integer_ratio() method

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

Output :

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with as_integer_ratio() method :  (-1, 1)
Decimal b with as_integer_ratio() method :  (142857, 1000000)

Code #2 : Example for as_integer_ratio() method

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

Output :

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


Decimal a with as_integer_ratio() method :  (-157, 50)
Decimal b with as_integer_ratio() method :  (32100000, 1)
