which is supposed to convert a string to an integer, does not compile. Can you fix it? `var s: string = "123"; var i: int = int(s)` Yes, the code you provided is not valid Nim syntax. In order to convert procedure from the strutils module. Here is an example of how to use it: import strutils var s: string = "123" var i: int = parseInt(s) echo i # Output: 123 In this example, we import the strutils module we would write it like from std/strformat import fmt const DefaultWorldRange = [0.0, 0, 800, 600] var str: string for i, x in pairs(DefaultWorldRange): str.add(fmt("{x:g}")) if i < DefaultWorldRange
