This is the biggest problem I had with CGFloat: while it is nice at first to have a type that adapts to the device word size it runs on, I prefer to always have an explicit accuracy guarantee than worrying about my CGFloat code changing in behaviour when it runs on a 32 bit device rather than a 64 bit one.
There are lots of things that are unfortunate about CGFloat. I don’t see how they translate to Float and Double.
