代碼#1:is_subnormal()方法示例
# 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())
輸出:
Decimal value a: -1 Decimal value b: -Infinity Decimal a with is_subnormal() method: False Decimal b with is_subnormal() method: False
代碼2:is_subnormal()方法示例
# 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())
輸出:
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
