Why would you want this in pawn?
What is the use for it?

I try to do and i made this
PHP код:
stock HSVtoRBG(H,S,V) //H = 0 to 360 - S = 0 to 100 - V = 0 to 100
{
new Float:fS,Float:sV;
fS = S/100;
sV = V/100;
if (H < 0) H += 360;
if (H >= 360) H -= 360;
new Float:r, Float:g, Float:b;
if (sV <= 0) r = 0,g = 0, b = 0;
else if (fS <= 0) r = sV, g = sV, b = sV;
else
{
new Float:hf = H / 60.0;
new i = floatround(hf);
new Float:f = hf - i;
new Float:pv = sV * (1 - fS);

case 5: r = sV,g = pv,b = qv;
// Just in case we overshoot on our math by a little, we put these here. Since its a switch it won't slow us down at all to put these here.

case -1: r = sV,g = pv,b = qv;
// The color is not defined, we should throw an error.
