Python math.tanh()方法 (Python math.tanh() method)

math.tanh() method is a library method of math module, it is used to get the hyperbolic tangent of given number in radians, it accepts a number and returns hyperbolic tangent.

math.tanh()方法是數(shù)學(xué)模塊的庫方法，用于獲取以弧度為單位的給定數(shù)字的雙曲正切值，它接受一個數(shù)字并返回雙曲正切值。

Note: math.tanh() method accepts only numbers, if we provide anything else except the number, it returns error TypeError – "TypeError: a float is required".

注意： math.tanh()方法僅接受數(shù)字，如果我們提供除數(shù)字以外的任何其他內(nèi)容，它將返回錯誤TypeError – “ TypeError：需要浮點(diǎn)數(shù)” 。

Syntax of math.tanh() method:

math.tanh()方法的語法：

math.tanh(x)

Parameter(s): x – is the number whose hyperbolic tangent to be calculated.

參數(shù)： x –是要計(jì)算其雙曲正切值的數(shù)字。

Return value: float – it returns a float value that is the hyperbolic tangent value of the number x.

返回值： float-返回一個浮點(diǎn)值，該值是數(shù)字x的雙曲正切值。

Example:

例：

Input:x = 1.5# function callprint(math.tanh(x))Output:0.9051482536448664

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

# Python code to demonstrate example of # math.tanh() method# importing math module import math # number x = -10 print("math.tanh(",x,"): ", math.tanh(x))x = 0 print("math.tanh(",x,"): ", math.tanh(x))x = 1.5 print("math.tanh(",x,"): ", math.tanh(x))x = 5 print("math.tanh(",x,"): ", math.tanh(x))x = 15.45 print("math.tanh(",x,"): ", math.tanh(x))

Output

輸出量

math.tanh( -10 ): -0.9999999958776927 math.tanh( 0 ): 0.0 math.tanh( 1.5 ): 0.9051482536448664 math.tanh( 5 ): 0.9999092042625951 math.tanh( 15.45 ): 0.999999999999924

TypeError example

TypeError示例

# Python code to demonstrate example of # math.tanh() method with exception# importing math module import math # number x = "2.5" print("math.tanh(",x,"): ", math.tanh(x))

Output

輸出量

Traceback (most recent call last):File "/home/main.py", line 9, in <module>print("math.tanh(",x,"): ", math.tanh(x)) TypeError: a float is required
