Swift - nexttoward() Function
The Swift nexttoward() function returns the next representable value after first argument in the direction of second argument.
Syntax
In Foundation framework, it is defined as follows:
public func nexttoward(_ __x: Double, _ __y: Float80) -> Double
Parameters
x |
Specify the base value. |
y |
Specify the value toward which the return value is approximated. |
Return Value
Returns the next representable value after first argument in the direction of second argument.
Example:
The example below shows the usage of nexttoward() function.
import Foundation
print("nexttoward(0.8, 1) = \(nexttoward(0.8, 1))")
print("nexttoward(0.8, 0) = \(nexttoward(0.8, 0))")
print("nexttoward(-0.8, -1) = \(nexttoward(-0.8, -1))")
print("nexttoward(-0.8, 0) = \(nexttoward(-0.8, 0))")
The output of the above code will be:
nexttoward(0.8, 1) = 0.8000000000000002 nexttoward(0.8, 0) = 0.7999999999999999 nexttoward(-0.8, -1) = -0.8000000000000002 nexttoward(-0.8, 0) = -0.7999999999999999
