Convert float value to String in Swift

If you want some more control of how it’s converted you can either use +stringWithFormat on NSString or NSNumberFormatter

let f = -33.861382
let s = NSString(format: "%.2f", f)

let nf = NSNumberFormatter()
nf.numberStyle = .DecimalStyle
// Configure the number formatter to your liking
let s2 = nf.stringFromNumber(f)
