cbrt() in swift

The cbrt() function returns the cube root of a number. It is an inbuilt function in Swift. The cbrt() function in Swift returns the cube root of a number. Using the cbrt() function in Swift, we can calculate the cube root of any natural, decimal, and negative number (perfect and non-perfect cubes).

Syntax:

// return cube root of number

// number can be of any type int, float and double

// the return type is same as parameter passed

// number passed can be integer, perfect cube root or non-perfect cube root

cbrt(number)

Parameter: The parameter can be of int, float or double type.

Return value: cbrt() function returns the cube root of a number. The datatype of the return value is the same as we pass in the parameter.

Examples:

Input: 64.00

Output: 4.0

Input: 0.0

Output: 0.0

Input: 9

Output: 2.08008

Below is given program to illustrate the cbrt() function:

Swift

// Swfit Program to implement cbrt()
import Swift
import Foundation

// Perfect cube root
print ("The value of cbrt(64.00) : ", cbrt(64.00));

// whole number
print ("The value of cbrt(0.0) : ", cbrt(0.0));

// natural number
print ("The value of cbrt(10.00) : ", cbrt(10.00));

// Non-perfect cube root
print ("The value of cbrt(9.2) : ", cbrt(9.2));

// Negative number
print ("The value of cbrt(-3.7) : ", cbrt(-3.7));

Output:

The value of cbrt(64.00) :  4.0
The value of cbrt(0.0) :  0.0
The value of cbrt(10.00) :  2.1544346900318834
The value of cbrt(9.2) :  2.0953791063432945
The value of cbrt(-3.7) :  -1.5466803737720356...
