Kotlin has an excellent feature called string templates.
val i = 10
val s = "i = $i" // evaluates to "i = 10"
But is it possible to have any formatting in the templates? For example, I would like to format Double in string templates in kotlin, at least to set a number of digits after a decimal separator:
val pi = 3.14159265358979323
val s = "pi = $pi??" // How to make it "pi = 3.14"?
