代码 #1：radix() 方法的示例

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

输出 ：

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with radix() method :  10
Decimal b with radix() method :  10

代码 #2：radix() 方法的示例

# Python Program explaining 
# radix() method
  
# loading decimal library
from decimal import *
  
  
# Initializing a decimal value
a = Decimal('-3.14545454')
  
b = Decimal('321e + 5')
  
  
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
  
  
# Using Decimal.radix() method
print ("\n\nDecimal a with radix() method : ", a.radix())
  
print ("Decimal b with radix() method : ", b.radix())

输出 ：

Decimal value a :  -3.14545454
Decimal value b :  3.21E+7


Decimal a with radix() method :  10
Decimal b with radix() method :  10
