带有Python示例的math.exp()方法
Python math.exp()方法 (Python math.exp() method)
math.exp() method is a library method of math module, it is used to get the number in exponential form, it accepts a number and returns the number in the exponential format (if the number is x, it returns e**x.
math.exp()方法是math模塊的庫方法,用于獲取指數形式的數字,它接受一個數字并以指數格式返回該數字(如果數字為x ,則返回e ** x 。
Note: If anything is passed except the number, the method returns a type error, "TypeError: a float is required".
注意:如果傳遞了除數字以外的任何內容,則該方法將返回類型錯誤“ TypeError:需要浮點數”。
Syntax of math.exp() method:
math.exp()方法的語法:
math.exp(n)Parameter(s): n – an integer or a float number.
參數: n-整數或浮點數。
Return value: float – it returns a float value that is an exponential form of the number n.
返回值: float –它返回一個浮點數,該浮點數是數字n的指數形式。
Example:
例:
Input:a = 111.111# function callprint(math.exp(a))Output:1.7984326512709283e+48Python代碼演示math.exp()方法的示例 (Python code to demonstrate example of math.exp() method)
