When I put this in my code in swift 3 with xcode :

myarray.append(99.1)

I have following result when I use print(myarray) command for my array:

99.099999999999994

I would like to have only 99.1 no more. How can I add a value like 99.1 without being transform to the longer value in an array?

Doubles and Floats will both lose precision. Try taking a look at NSDecimalNumber. We deal with money in our app and it's a bit more complicated to use but is the only way to go. – Micah Wilson Jan 04 '17 at 06:14
