I tested that against my one-liner:
static inline function myFloor(f:Float){
return f > 0 ? Std.int(f) : Std.int(f)-1;
}
Both compiled with hAxe: mine ran 6x faster. (10 million loop with +/- pi)
#include <stdio.h>
char*p="#include <stdio.h>%cchar*p=%c%s%c;%cmain() {printf(p,10,34,p,34,10);}";
main() {printf(p,10,34,p,34,10);}
Although, for larger values that "fast" floor function takes more time, while my function and even Math.floor take only a constant time to run for any value.
I really have no idea why that fastFloor function would be considered faster.
#include <stdio.h>
char*p="#include <stdio.h>%cchar*p=%c%s%c;%cmain() {printf(p,10,34,p,34,10);}";
main() {printf(p,10,34,p,34,10);}

In summer '08 we wanted to do a programming collab where everyone makes some part of a shooter. The art there is by Xeptic and most by Luis.
Unfortunately the level of ability then was such that it took me some time just to spoonfeed El-Presidente how to make the exploding asteroids in AS3.
Also then (as now) my programming style makes grown men cry.
Before that I was working on this with Luis. http://gust.isjackd.in/ng/_shooter.swf
But then he got tired of it and decided he wants to do the collab instead.

Doh! Stupid edge cases.. But even if you added an entire check for that, it would still be faster than fastFloor.
#include <stdio.h>
char*p="#include <stdio.h>%cchar*p=%c%s%c;%cmain() {printf(p,10,34,p,34,10);}";
main() {printf(p,10,34,p,34,10);}

If what you have said is true, quite possibly. I mean, the code is so horribly unoptimised it makes me cry. They could have totally removed the "f--" and "f++" bits of that code (since 'f' is no longer used afterwards), which would have made it so much faster!

I didn't check its speed, I was shocked that something so large could be fast. I know that Math functions are usually extremely slow, the trig functions, Math.abs(), ect. It wouldn't surprise me if it was much faster than Math.floor(), but I did doubt its speed.
It seems like the haXe community has let me down :(
That fastFloor() function uses a partially unrolled loop. Thing is, you don't need any kind of loop to compute the floor of a number. So either the person who made that is delusional, or it was used it some bizarre context.
#include <stdio.h>
char*p="#include <stdio.h>%cchar*p=%c%s%c;%cmain() {printf(p,10,34,p,34,10);}";
main() {printf(p,10,34,p,34,10);}
It was probably just a example of how a floor could be made.

Well, I found this: http://haxe.org/doc/flash/cheatsheet?ver sion=8376
But notice how that fastFloor function only exists for a few versions of that page.
#include <stdio.h>
char*p="#include <stdio.h>%cchar*p=%c%s%c;%cmain() {printf(p,10,34,p,34,10);}";
main() {printf(p,10,34,p,34,10);}

And another mystery solved by the Flash Reg Crew! Nice job guys, let's go home.

greetings everyone!
I've been around newgrounds and looking into the flash scene off and on since '06 with a few different aliases, but I've never really been an active member. I'm getting more serious about game development now so I just wanted to pop in and introduce myself.
So, how's everyone doing?

I have a bit of a sunburn.
