代碼1：next_toward()方法示例

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

輸出：

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with next_toward() method :  -0.9999999999999999999999999999
Decimal b with next_toward() method :  0.142857

代碼2：next_toward()方法的示例

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

輸出：
