Python|小数调整（）方法

Decimal#adjusted() ：adjusted()是一个 Decimal 类方法，它在移出系数最右边的数字直到只剩下前导数字后返回调整后的指数

Syntax: Decimal.adjusted()

Parameter: Decimal values

Return: the adjusted exponent after shifting out the coefficient’s rightmost digits until only the lead digit remains.

代码 #1：adjusted() 方法的示例

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

输出 ：

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with adjusted() method :  0
Decimal b with adjusted() method :  -1

代码 #2：adjusted() 方法的示例

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

输出 ：

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


Decimal a with adjusted() method :  0
Decimal b with adjusted() method :  7
