Ruby CMath tanh() Method with example

  • Last Updated : 08 Jan, 2020

tanh() method is Math class which is used to returns the hyberbolic tangent of the given value.

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.

Example #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"

Output:




//Write Java code here
tanh value of a : 0.3438039328469827

tanh value of b : 0.9640275800758169

Example #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"

Output:

tanh value of a : 0.0

tanh value of b : -0.24209655276165779
