Swift - tanh() Function
The Swift tanh() function returns hyperbolic tangent of a value. The hyperbolic tangent of x is defined as:
where e is an Euler's number.
Syntax
In Foundation framework, it is defined as follows:
public func tanh(_ x: CGFloat) -> CGFloat public func tanh(_ x: Float) -> Float public func tanh(_ x: Float80) -> Float80 public func tanh(_ __x: Double) -> Double
Parameters
x |
Specify the value. |
Return Value
Returns the hyperbolic tangent of a value.
Example:
In the example below, tanh() function is used to find out the hyperbolic tangent of a value.
import Foundation
print("tanh(-4.0) = \(tanh(-4.0))")
print("tanh(-2.0) = \(tanh(-2.0))")
print("tanh(0.0) = \(tanh(0.0))")
print("tanh(2.0) = \(tanh(2.0))")
print("tanh(4.0) = \(tanh(4.0))")
The output of the above code will be:
tanh(-4.0) = -0.999329299739067 tanh(-2.0) = -0.9640275800758169 tanh(0.0) = 0.0 tanh(2.0) = 0.9640275800758169 tanh(4.0) = 0.999329299739067
