Forums Scripts & Popups binary --> Hex

I need a script that would convert bin to hex. I tried alot of if's but now i need a way to make it without using like: if(%bin = 1111) out = "F"
bcus if its 100 pixels wide thats alot of ifs. Can anyone help me with this?

$base(the_binary_number,2,16)

Thanks, just figured that out, i gues maybe i should have looked a little harder...
