So... I've been trying to program a Sonic the Hedgehog style 360� momentum physics engine... As you may or may not know, this involves quite a bit of complex math equations and trigonometry...

Anyway, what i'm trying to do is limit the amount of decimal digits on a certain value (For instance, if the value is 1.4039034523; It becomes 1.404 instead) But as far as i know, construct's "Round" function rounds the number up to... Well, a round number... So how do i do this?
