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)

CodePudding user response：

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

import Foundation

  ⋮
  ⋮
  ⋮

print(total.formatted())

CodePudding user response：

you could just do this:

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

CodePudding user response：

• 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))

• Use String formatter when printing

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)!)

I got it working but changing the code to this

var runningNumber:Double = 5
var currentValue:Double = 2
var total:Double =  NSNumber(value: runningNumber   currentValue).stringValue

print(total)
