Round Issue in swift

Question

I have this Info.

let params2: [String: AnyObject] = [
    \"app_token\": myapptoken,
    \"member_access_token\": accessToken!,
    \"pay_process\": 0,
             


        

Answer 1

The problem lies within the numeric precission, simply put, some numbers cannot be defined as a Double without losing precision.

Instead you should use NSDecimalNumber:

let num = NSDecimalNumber(string: "9.87")
