语法: Decimal.is_infinite()
参数:十进制值
返回:true–如果十进制值为无穷大值；否则为假
代码# 1:is _ infinite()方法示例
# Python Program explaining
# is_infinite() 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_infinite() method
print ("\n\nDecimal a with is_infinite() method : ", a.is_infinite())
print ("Decimal b with is_infinite() method : ", b.is_infinite())
输出:
Decimal value a : -1
Decimal value b : -Infinity
Decimal a with is_infinite() method : False
Decimal b with is_infinite() method : True
代码# 2:is _ infinite()方法示例
# Python Program explaining
# is_infinite() 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_infinite() method
print ("\n\nDecimal a with is_infinite() method : ", a.is_infinite())
print ("Decimal b with is_infinite() method : ", b.is_infinite())
输出:
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with is_infinite() method : False
Decimal b with is_infinite() method : False
