Python math.pow()方法 (Python math.pow() method)

math.pow() method is a library method of math module, it is used to calculate the given power of a base, it accepts two numbers and returns the first number to the power of the second number in the float.

math.pow()方法是數學模塊的庫方法，用于計算基數的給定冪，它接受兩個數字并將第一個數字返回為浮點數中第二個數字的冪。

Syntax of math.pow() method:

math.pow()方法的語法：

math.pow(a, b)

Parameter(s): a, b – the numbers whose power needs to be calculated (Here, a is the base and b is the power to calculate the result a to the power of b).

參數： a，b –需要計算其冪的數字(此處， a是基數， b是將結果a乘以b的冪的冪)。

Return value: float – it returns a float value that is the a to the power of b.

返回值： 浮法 -它返回一個浮點值，它是A到B的力量。

Example:

例：

Input:a = 2b = 3# function callprint(math.pow(a, b))Output:8.0

Python代碼演示math.pow()方法的示例 (Python code to demonstrate example of math.pow() method)

# python code to demonstrate example of # math.pow() method # importing math module import math # numbers a = 2 b = 3 # calculate a to the power of b print(a, " to the power of ", b, " is = ", math.pow(a,b))# numbers a = 2.2 b = 3.0 # calculate a to the power of b print(a, " to the power of ", b, " is = ", math.pow(a,b))# numbers a = 2 b = 0 # calculate a to the power of b print(a, " to the power of ", b, " is = ", math.pow(a,b))# numbers a = 0 b = 3 # calculate a to the power of b print(a, " to the power of ", b, " is = ", math.pow(a,b))

Output

輸出量

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
