using label as source for calcule swift [duplicate]

Question

In Obj C I used to use some code for pick up data from label, pull it in float and doing any calcul needed.

float chiffre1 = [[label1 text] floatValue];
float chiffre2 = [[label2 text] floatValue];

float number1 = chiffre1 + chiffre2;

Now in Swift I try to do the same thing but always end up with error. the code work very well in play ground, but when I use it in my app, and try to use data from a UILabel, doesn't work anymore.

@IBOutlet weak var DegreeLat1: UILabel!
@IBoutlet etc...

let deglat1 = DegreeLat1.text

let number2 = MinutLat1.text?.toInt()

let minlat1 = number2! / 60

let etc....

let lat1 = (degrelat1 + minlat1 + seclat1) * pi /180 // error "could not find an overload for "*" that accepts the supplied argument

let long1 = (etc...) * pi / 180

I tried many thing check almost everywhere can't find what I do wrong.

I am not sure what exactly you are trying to do but some things I found that looks wrong, you should include the errors you are finding to make it easier to help you.

let deglat1 = (DegreeLat1.text? as NSString).floatValue
let number2 = MinutLat1.text?.toInt()
let minlat1 = number2! / 60
let lat1 = (degrelat1 + minlat1 + seclat1) * M_PI / 180 

I hope that help!
