Swift - cosh() Function
The Swift cosh() function returns hyperbolic cosine of a value. The hyperbolic cosine of x is defined as:
where e is an Euler's number.
Syntax
In Foundation framework, it is defined as follows:
public func cosh(_ x: CGFloat) -> CGFloat public func cosh(_ x: Float) -> Float public func cosh(_ x: Float80) -> Float80 public func cosh(_ __x: Double) -> Double
Parameters
x |
Specify the value. |
Return Value
Returns the hyperbolic cosine of a value.
Example:
In the example below, cosh() function is used to find out the hyperbolic cosine of a value.
import Foundation print("cosh(-4.0) = \(cosh(-4.0))") print("cosh(-2.0) = \(cosh(-2.0))") print("cosh(0.0) = \(cosh(0.0))") print("cosh(2.0) = \(cosh(2.0))") print("cosh(4.0) = \(cosh(4.0))")
The output of the above code will be:
cosh(-4.0) = 27.308232836016487 cosh(-2.0) = 3.7621956910836314 cosh(0.0) = 1.0 cosh(2.0) = 3.7621956910836314 cosh(4.0) = 27.308232836016487
