Identifying Remainders in Developer Help

I trying to implement odd formulas (this one requiring the use of only remainders :) ) I need to check if the remainder of n divided by 4, equals 2 or 3.

How would I do this?

I'm starting to think this:

if(text2num(copytext("[Attacker.HPIV/4]",lentext("[Attacker.HPIV/4]")-1,lentext("[Attacker.HPIV/4]")))==2)
  ...


But it looks a little long...

if(n % 4 == 2 || n % 4 == 3)

If I understand what you want correctly, you should use the % operator. Something like the following should work:
mob/verb/Remainder()
    var/A = n%4
    if(A==2) world<<"The remainder is 2!"
    else if(A==3) world<<"The remainder is 3!"
    else world<<"The remainder is neither 2 or 3, but infact [A]!"


If you just want to know if it's 2 or 3, but doesn't matter which: 
if(n%4==2 || n%4==3)


*Edit*
Dratz, beaten again!

For integers, a simple if(n&2) will do. If you don't want to deal with bit flags, if(n%4>=2) works too.
