Use `parseBiggestUInt` proc in 
[strutils](https://nim-lang.org/docs/strutils.html#parseBiggestUInt,string)?

You can do like this: 
    
    
    import strutils
    
    let theint = stdin.readline.parseBiggestUInt
    

or 
    
    
    import strutils
    
    var theint = -1'u64
    try:
      theint = stdin.readline.parseBiggestUInt
    except ValueError:
      # do something
