带有Python示例的math.pow()方法
Pythonmath.pow()方法
math.pow()方法是数学模块的库方法,用于计算基数的给定幂,它接受两个数字并将第一个数字返回浮点数中第二个数字的幂。
它的语法math.pow()方法:
math.pow(a, b)
Parameter(s):a,b–需要计算其幂的数字(此处,a是基数,b是将结果a乘以b的幂的幂)。
返回值:float-它返回一个浮点值,即a乘以b的幂。
示例
Input: a = 2 b = 3 #函数调用 print(math.pow(a, b)) Output: 8.0
Python代码演示示例math.pow()方法
#python代码演示示例 # math.pow() method #导入数学模块 import math #数字 a = 2 b = 3 #计算a到b的幂 print(a, " to the power of ", b, " is = ", math.pow(a,b)) #数字 a = 2.2 b = 3.0 #计算a到b的幂 print(a, " to the power of ", b, " is = ", math.pow(a,b)) #数字 a = 2 b = 0 #计算a到b的幂 print(a, " to the power of ", b, " is = ", math.pow(a,b)) #数字 a = 0 b = 3 #计算a到b的幂 print(a, " to the power of ", b, " is = ", math.pow(a,b))
输出结果
2 to the power of 3 is = 8.0 2.2 to the power of 3.0 is = 10.648000000000003 2 to the power of 0 is = 1.0 0 to the power of 3 is = 0.0
