Swift - fma() Function
The Swift fma() function returns (x*y) + z. The function computes the result without losing precision and rounded only once to fit the result type.
Syntax
In Foundation framework, it is defined as follows:
public func fma(_ __x: Double, _ __y: Double, _ __z: Double) -> Double
Parameters
x |
Specify first value to multiplied. |
y |
Specify second value to multiplied. |
z |
Specify value to added. |
Return Value
Returns (x*y) + z.
Example:
The example below shows the usage of fma() function.
import Foundation
var x:Double = 2.1
var y:Double = 4.2
var z:Double = 10.3
print("(x * y + z) = \(fma(x, y, z))")
The output of the above code will be:
(x * y + z) = 19.12
