Swift - pow() Function
The Swift pow() function returns the base raise to the power of exponent.
Syntax
In Foundation framework, it is defined as follows:
public func hypot(_ x: CGFloat, _ y: CGFloat) -> CGFloat public func hypot(_ x: Float, _ y: Float) -> Float public func hypot(_ x: Float80, _ y: Float80) -> Float80 public func pow(_ __x: Double, _ __y: Double) -> Double public func pow(_ x: Decimal, _ y: Int) -> Decimal
Parameters
x |
Specify the base. |
y |
Specify the exponent. |
Return Value
Returns the base raise to the power of exponent.
if x is negative and y is a fraction, it returns -nan.
Example:
In the example below, pow() function is used to calculate the base raised to the power of exponent.
import Foundation
print("pow(2.0, 3.0) = \(pow(2.0, 3.0))")
print("pow(5.0, -3.0) = \(pow(5.0, -3.0))")
print("pow(10.0, 3.5) = \(pow(10.0, 3.5))")
print("pow(-10.0, 3.5) = \(pow(-10.0, 3.5))")
The output of the above code will be:
pow(2.0, 3.0) = 8.0 pow(5.0, -3.0) = 0.008 pow(10.0, 3.5) = 3162.2776601683795 pow(-10.0, 3.5) = -nan
