I 'm trying to make an application that calculates Bhaskara however I do not know what to do if the delta of an irrational number that is a root of a number , please help . my code like this :
// p.s: Code in Portugues
func bhaskara (#a: Double, b: Double, c: Double) -> (String) {
var Δ : Double = (b * b) - (4 * (a) * (c))
var raizDeDelta = sqrt(Δ)
var x1 : Double = (-b + raizDeDelta) / 2 * a
var x2 : Double = (-b - raizDeDelta) / 2 * a
var solucao = "S = {\(x2), \(x1)}"
var verificacaoSeONumeroEInfinito : Bool
if solucao == "S = {nan, nan}" {
solucao = "S = Ø"
}
if raizDeDelta.isInfinite {
}
return solucao
}
