Python|十进制 is_finite() 方法
Decimal#is_finite() : is_finite()是一个 Decimal 类方法,用于检查 Decimal 值是否为有限值。
Syntax: Decimal.is_finite()
Parameter: Decimal values
Return: true – if the Decimal value is finite value; otherwise false
代码 #1:is_finite() 方法的示例
# Python Program explaining
# is_finite() 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_finite() method
print ("\n\nDecimal a with is_finite() method : ", a.is_finite())
print ("Decimal b with is_finite() method : ", b.is_finite())
输出 :
Decimal value a : -1
Decimal value b : -Infinity
Decimal a with is_finite() method : True
Decimal b with is_finite() method : False
代码 #2:is_finite() 方法的示例
# Python Program explaining
# is_finite() 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_finite() method
print ("\n\nDecimal a with is_finite() method : ", a.is_finite())
print ("Decimal b with is_finite() method : ", b.is_finite())
输出 :
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with is_finite() method : True
Decimal b with is_finite() method : True
