代码1：的示例remainder_near()方法

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

输出：

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with remainder_near() method :  -0.000001
Decimal b with remainder_near() method :  0.000000

代码2：示例remainder_near()方法

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

输出：

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


Decimal a with remainder_near() method :  -3.14
Decimal b with remainder_near() method :  0E+5
