Do you think they [or you:suss:] chose width, as
lengthOfLength(s: String) = s.length.toString.lengthwould cause a meltdown.Dave Find Me On:Web|Facebook|Twitter|LinkedIn Folding Stats: Team CodeProject
I have to admit that "widthOfLength" seems OK to me. Obviously it is used to calculate the format/layout of some table perhaps where all the lengths are scanned to find the longest/widest. It is just a matter of semantics.
- I would love to change the world, but they won’t give me the source code.

You're absolutely right about the code purpose.:thumbsup:

Trying to determine how many decimal digits are required for the Length? A trick a colleague showed me once is to get the log 10 of the Length. Something like:
int y = (int) System.Math.Ceiling ( System.Math.Log10 ( new string ( '*' , 255 ).Length ) ) ; -

I don't understand language of your tribe, but I would go with extension method in C#. Something like this:
public static Int32 GetStringLength(this Int32 value)s.Length.GetStringLength():DSmart K8 wrote:

It's Scala actually and both Forogar and PIEBALDconsult are right about the function purpose. It is taken from a small example that reads a text file and prints it out displaying each line's length before it and the function makes sure that all lines are aligned/tabulated correctly.
