Ruby CMath tanh() 方法与示例

tanh() 方法是 Math 类，用于返回给定值的双曲正切值。

Syntax: Math.tanh(z)

Parameter: Here, z is the value whose hyberbolic tangent is to be calculated.

Returns: This method returns the hyberbolic tangent value of the z.

示例 #1：

# Ruby code for tanh() method
require 'cmath'
  
# Initializing variable    
a = 0.3584
b = 2
       
puts "tanh value of a : #{CMath.tanh(a)}\n\n"
       
puts "tanh value of b : #{CMath.tanh(b)}\n\n"

输出：

//Write Java code here

tanh value of a : 0.3438039328469827

tanh value of b : 0.9640275800758169

示例 #2：

# Ruby code for tanh() method
require 'cmath'
  
# Initializing variable    
a = 0
b = -0.247
       
puts "tanh value of a : #{CMath.tanh(a)}\n\n"
       
puts "tanh value of b : #{CMath.tanh(b)}\n\n"

输出：

tanh value of a : 0.0

tanh value of b : -0.24209655276165779
