rgb to hex conversion

[Inhumanoid]

Anybody got a good rgb to hex conversion routine in ASP or javascript ?

This isnt the most efficient code but it does the job.

function Num2Hex(n){

if (n==0) return "0";
if (n==1) return "1";
if (n==2) return "2";
if (n==3) return "3";
if (n==4) return "4";
if (n==5) return "5";
if (n==6) return "6";
if (n==7) return "7";
if (n==8) return "8";
if (n==9) return "9";
if (n==10) return "A";
if (n==11) return "B";
if (n==12) return "C";
if (n==13) return "D";
if (n==14) return "E";
if (n==15) return "F";

}

function rgb2Hex(r,g,b) {

var r1,r2,g1,g2,b1,b2

if (r>15)
r1=Num2Hex(Math.floor(r/16));                                                    
else
r1=Num2Hex(0);

r2=Num2Hex(r-16*Math.floor(r/16));

if (b>15)
b1=Num2Hex(Math.floor(b/16));                                                    
else
b1=Num2Hex(0);

b2=Num2Hex(b-16*Math.floor(b/16));

if (g>15)
g1=Num2Hex(Math.floor(g/16));                                                    
else
g1=Num2Hex(0);

g2=Num2Hex(g-16*Math.floor(g/16));




return "#"+r1+r2+g1+g2+b1+b2;

}
