Ruby | Math atanh() function

  • Last Updated : 07 Jan, 2020

The atanh() is an inbuilt function in Ruby returns the inverse hyperbolic tangent of an angle given in radians. It accepts values in the range [-1, +1] and returns in the range [-INFINITY, INFINITY].

Syntax: Math.atanh(value)

Parameters: The function accepts one mandatory parameter value which specifies the inverse hyperbolic angle in radian which lies in the range [-1, 1].

Return Value: It returns the inverse hyperbolic tangent of an angle given in radians

Example 1:






#Ruby program for atanh() function
  
#Assigning values
val1 = -1 val2 = 1 val3 = -0.5 val4 = 0.7
  
#Prints the atanh() value
                                      puts Math.atanh(val1)
                                          puts Math.atanh(val2)
                                              puts Math.atanh(val3)
                                                  puts Math.atanh(val4)

Output:

 -Infinity
Infinity
-0.5493061443340548
0.8673005276940531

Example 2:




#Ruby program for atanh() function
  
#Assigning values
val1 = -0.7 val2 = 0.6 val3 = -0.56 val4 = 0.90
  
#Prints the atanh() value
                                           puts Math.atanh(val1)
                                               puts Math.atanh(val2)
                                                   puts Math.atanh(val3)
                                                       puts Math.atanh(val4)

Output:

-0.8673005276940531
0.6931471805599453
-0.632833186665638
1.4722194895832204
