How to convert a float to a CGFloat
Swift version: 5.10
The Float and CGFloat data types sound so similar you might think they were identical, but they aren't: CGFloat is flexible in that its precision adapts to the type of device it's running on, whereas Float is always a fixed precision. Thus, you never lose precision converting from Float to CGFloat, whereas you might going the other way.
To convert, just use the CGFloat constructor, like this:
let myCGFloat = CGFloat(myFloat)
