![]() Some types can have a special internal representation for example, numbers, characters and booleans can be represented as primitive values at runtime but to the user they look like ordinary classes. If let dotIndex = stringFromNumber.range(of: ".")?. In Kotlin, everything is an object in the sense that you can call member functions and properties on any variable. Second, people tend to test one's own code with examples which works as expected, even if it is known that the code would not work as expected for some other examples. Alternatively, we can also use the double dots (.) operator to define a range of values. Kotlin provides the rangeTo and downTo functions to create a range. In Double, 6.1699999999999999 is exactly equivalent to 6.17. Range expressions in Kotlin help to iterate over a range. ![]() ![]() First of all, you should bettter not use `Double` when you want to control all the behavior abount rounding.Īt any time, calculations on Double or converting Double to decimal representation would cause binary rounding, which may not be as expected from the decimal point of views. Instead of this boiler code, Kotlin Ranges could be used to repeat a set of statements, starting with a value on lower or upper limit and progressing towards. ![]()
