代码 #1:is_subnormal() 方法的示例
# Python Program explaining
# is_subnormal() method
# loading decimal library
from decimal import *
# Initializing a decimal value
a = Decimal(-1)
b = Decimal('-inf')
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
# Using Decimal.is_subnormal() method
print ("\n\nDecimal a with is_subnormal() method : ", a.is_subnormal())
print ("Decimal b with is_subnormal() method : ", b.is_subnormal())
输出 :
Decimal value a : -1
Decimal value b : -Infinity
Decimal a with is_subnormal() method : False
Decimal b with is_subnormal() method : False
代码 #2:is_subnormal() 方法的示例
# Python Program explaining
# is_subnormal() 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.is_subnormal() method
print ("\n\nDecimal a with is_subnormal() method : ", a.is_subnormal())
print ("Decimal b with is_subnormal() method : ", b.is_subnormal())
输出 :
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with is_subnormal() method : False
Decimal b with is_subnormal() method : False
