How do I remove ".0" from a Double when printing in Swift? – Ios swift

Below is my code.. I am doing 5 + 2 and I would like the output to be 7 but I am getting 7.0. Can someone please help me and tell me why

var runningNumber:Double = 5
var currentValue:Double = 2
var total:Double = Double(runningNumber + currentValue)
print(total)

    I got it working but changing the code to this

    import UIKit

var runningNumber:Double = 5.3
var currentValue:Double = 2
var total:String =  NSNumber(value: runningNumber + currentValue).stringValue

print(total)

    you could just do this:

     print(String(format:"%0.0f", total))

    Consider using .formatted() to format the floating point number properly for you:

    import Foundation

  ⋮
  ⋮
  ⋮

print(total.formatted())

    • Use Ints instead of Doubles
    let two = 2
let five = 5
print(two + five)
    • Cast to Int when printing
    let two: Double = 2
let five: Double = 5
print(Int(two + five))
    • Format to a string with zero fraction digits
    let two: Double = 2
let five: Double = 5
print(String(format: "%.0f", two + five))
    • Use NumberFormatter
    let two: Double = 2
let five: Double = 5

let formatter = NumberFormatter()
formatter.numberStyle = .decimal
formatter.maximumFractionDigits = 0

let sum = NSNumber(value: two + five)
print(formatter.string(from: sum)!)
