代码# 1:is _ zero()方法示例
# Python Program explaining
# is_zero() method
# loading decimal library
from decimal import *
# Initializing a decimal value
a = Decimal(-1)
b = Decimal(0)
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
# Using Decimal.is_zero() method
print ("\n\nDecimal a with is_zero() method : ", a.is_zero())
print ("Decimal b with is_zero() method : ", b.is_zero())
输出:
Decimal value a : -1
Decimal value b : 0
Decimal a with is_zero() method : False
Decimal b with is_zero() method : True
代码# 2:is _ zero()方法示例
# Python Program explaining
# is_zero() method
# loading decimal library
from decimal import *
# Initializing a decimal value
a = Decimal(-0)
b = Decimal('321e + 5')
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
# Using Decimal.is_zero() method
print ("\n\nDecimal a with is_zero() method : ", a.is_zero())
print ("Decimal b with is_zero() method : ", b.is_zero())
输出:
Decimal value a : 0
Decimal value b : 3.21E+7
Decimal a with is_zero() method : True
