Printed double value differs from originally set value

Question

I am adding two array which contains double values

 let arrayA = [1.1,2.3]
 let arrayB = [4.2,5.5,6.8]

 let c = arrayA + arrayB

 print(\"\\(c)\");
         


        

Answer 1

You don't. It's the way Double (and Float) does work.

As workaround you can round your values when you are going to print them

for num in c {
    print(String(format: "%.1f", num))
}

1.1

2.3

4.2

5.5

6.8
