I try to convert a String decimal like "1.10" to Double object but when I use 

    Double("1.10") result is wrong 1.1000000000000001

but if I use 

    Double("1.02") result is ok : 1.02

Did i miss something ?

I use the simulator iPhone XS in Swift 5.0 and Xcode 10.1

    What you are missing is that `Double` is a *binary* floating point number, and cannot represent all numbers exactly. – Martin R Apr 26 '19 at 21:06
