 if (temp == 10)

  temp = 'A';

 else if (temp == 11)

}

The result I get is 5e-3248e-3231.285e-3212.0553e-3203.2885e-3195.2616e-3188.4185624e-3171.346969984e-3152.155151975e-3143.4482431603e-3135.51718905651e-3128.8275024904155e-3111.412400398466485e-3092.

for 65... which is no doubt because I don't know how to keep the result an integer.

Could someone help me out with the code. I don't know what to do with it from here.

It is a decimal to base 16 conversion.

Try this, change

sum = sum / 16;

to

sum = Math.floor(sum/16);

that will truncate any decimal parts of "sum".

Shit, slime so easy, can't believe I missed it, thanks a lot.

Why complicate things?

hex = (255).toString(16);
octal = (255).toString(8);
binary = (255).toString(2);

Enjoy!

You're kidding! I didn't know toString took an argument... wish I had known that before...

They have an easy way to go from base 16 back to base 10?

That was a neet little trick there max, saves a ton of time, or would have, had I not already attempted to code it the other way.

I suppose one could try ("4A3F").toValue(16); a try, but it's really a shot in the dark, and probably won't work...

People, you're forgetting parseInt()...

parseInt("FF", 16);
parseInt("377", 8);
parseInt("11111111", 2);

Enjoy!

threep wishes he was in the forum a little earlier so he could provide at least ONE helpful post before mr 'fount of all coding knowledge' max does....

it's amazig how you gys shortened the code. but wat is it good for?
k10


only change remains
