Determining a specific number in Developer Help

Okay, my question is how would I determine the first, second, and third didgit number using code. Like if I needed to check if the second number of src.velocity was to determine the icon state of something.

I suppose if I were a better coder I would know how to use len to figure this out but unfortunetly I'm not so, how would I go about doing this?

NOTE: Yeah I used search, couldn't find anything relevant though.

Turn it into a string and use copytext(), findtext(), or text2ascii().

Any reason why
mob
    verb
        testverb()
            var/Q = num2text(src.velocity)
            src<<"<b>[Q]"

returns a number?

First digit is round(n/100). Second digit is round((n%100)/10). Third digit is round(n%10).

Note that that does assume it's only three digits. If it can be more, the first one would be round((n%1000)/100). But that wouldn't be the "first" digit.

That's a good approach as long as the number will not turn into something like "1.2e1" or "12.345".

In that case, math on it will not be accurate anyways.
