代码 #1：next_plus() 方法的示例

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

输出 ：

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with next_plus() method :  -0.9999999999999999999999999999
Decimal a with next_plus() method :  -0.9999999999999999999999999999
Decimal b with next_plus() method :  0.1428570000000000000000000001

代码 #2：next_plus() 方法的示例

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

输出 ：

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