Ruby - Math.atanh() Method
The Ruby Math.atanh() method returns inverse hyperbolic tangent of a value. The inverse hyperbolic tangent of x is defined as:
Syntax
Math.atanh(x)
Parameters
x |
Specify the value in range [-1, 1]. |
Return Value
Returns the inverse hyperbolic tangent of a value.
If the x is not in the range of [-1, 1], DomainError is thrown.
If the x is -1, it returns -Infinity.
If the x is 1, it returns Infinity.
Example:
In the example below, Math.atanh() method is used to find out the inverse hyperbolic tangent of a value.
puts "Math.atanh(-1) = #{Math.atanh(-1)}"
puts "Math.atanh(-0.5) = #{Math.atanh(-0.5)}"
puts "Math.atanh(0) = #{Math.atanh(0)}"
puts "Math.atanh(0.5) = #{Math.atanh(0.5)}"
puts "Math.atanh(1) = #{Math.atanh(1)}"
The output of the above code will be:
Math.atanh(-1) = -Infinity Math.atanh(-0.5) = -0.5493061443340548 Math.atanh(0) = 0.0 Math.atanh(0.5) = 0.5493061443340548 Math.atanh(1) = Infinity
