swift
Parameters: num: Double
Input num should be a Double type number
Returns: Double: the cube root of input num
The findCubeRoot function takes one parameter, a number, and returns its cube root. It's written in Swift, commonly used for iOS app development.
Hello programmer, welcome to this informative blog post. Here, we aim to provide a clear and concise walkthrough on how to create a function in Swift to identify the cube root of a given number. Stay tuned, we hope these simple steps will help you grasp this concept and improve your Swift programming skills.
Firstly, we must understand the problem at hand which is to calculate the cube root of a given number. The cube root of a number is that value which when multiplied three times gives the original number.
let number = 8
Next, we need to define a function which accepts one argument (the number for which we are to find the cube root) and returns a type Double since the cube root may be a fraction.
func findCubeRoot(of number: Double) -> Double {
// Function body will go here
}
In Swift, we can use the pow function to calculate the cube root. The pow function requires 2 parameters, the number and the power. To calculate the cube root, the power will be 1/3.
let cubeRoot = pow(number, 1.0 / 3.0)
Finally, we need to return this calculated cube root from our function.
return cubeRoot
Putting it all together, the following is the full implementation of the function in Swift to find the cube root of a number.
func findCubeRoot(of number: Double) -> Double {
let cubeRoot = pow(number, 1.0 / 3.0)
return cubeRoot
}
let root = findCubeRoot(of: 8)
print(root)
Cube root is the inverse operation of cubing a number. For a number `x`, cube root of `x` is a value `y` such that `y*y*y` equals `x`. This function makes use of this mathematical principle to derive the cube root using the built-in `pow` function.
