[AS3] <between> command?

i'm pretty sure there is no <is in between this number give or take 5 values> command, so how would i say:

Actionscript Code:

_root.mcMain.y <is in between> this.y <plus or minus> 5

thanks for all help -- much appreciated!

Code:

---

if (_root.mcMain.y>this.y-5&&_root.mcMain.y<this.y+5) {
        // do whatever
}

---

ahh yes thank you! i feel dumb now -- i was using || instead of &&

thanks again

if (Math.abs (_root.mcMain.y - this.y) < 5) would work too

ahh yes that's what i was looking for, but i couldn't get it to work lol so i tried the other suggestion and screwed it up with || not &&. but thanks!
