代码#1:调整()方法示例
# 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:调整()方法示例
# 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
