Ruby | Math atanh() function Last Updated : 07 Jan, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report 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: CPP #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: CPP #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 Reference: https://devdocs.io/ruby~2.5/math#method-c-atanh Comment More infoAdvertise with us Next Article Ruby | Math atanh() function G gopaldave Follow Improve Article Tags : Ruby Ruby-Methods Ruby Collections Ruby Math-class Similar Reads Ruby | Math atan() function The atan() is an inbuilt function in Ruby returns the arc tangent of a number means give a tangent value to this function it will return the angle in radian corresponding to that value. arc tangent is the inverse operation of tangent.
