Swift - cbrt() Function



The Swift cbrt() function returns the cube root of the given number.

Syntax

In Foundation framework, it is defined as follows:

public func cbrt(_ x: CGFloat) -> CGFloat
public func cbrt(_ x: Float) -> Float
public func cbrt(_ x: Float80) -> Float80
public func cbrt(_ __x: Double) -> Double

Parameters

x Specify a number.

Return Value

Returns the cube root of the specified number.

Example:

In the example below, cbrt() function is used to find out the cube root of the given number.

import Foundation

print("cbrt(-64.0) = \(cbrt(-64.0))")
print("cbrt(8.0) = \(cbrt(8.0))")
print("cbrt(125.0) = \(cbrt(125.0))")
print("cbrt(500.0) = \(cbrt(500.0))")

The output of the above code will be:

cbrt(-64.0) = -4.0
cbrt(8.0) = 2.0
cbrt(125.0) = 5.0
cbrt(500.0) = 7.937005259840998
