Returns the opposite of any number, can be a floating number too.

Math.toOpposite = function(){
if(!arguments[0]){
return false;
}
var lenum = arguments[0].toString();
if(!lenum.match(/\d/)){
return false;
}
if(lenum.match(/^-/)){
lenum = parseFloat(lenum);
lenum = this.abs(lenum);
} else {
lenum = '-'+lenum;
lenum = parseFloat(lenum);
}
return lenum;
}

Used like:
Math.toOpposite(number)

Enjoy.

Then use parseInt with a base of 2 on a binary number and then use the method.

Pretty much Nate.

Also, Moose, what about negative binary numbers? Does this work with them?

Can't you just multiply the number by -1?

Why?

First of all, this is in a code, and secondly, you just need to add (or remove) a negative sign on the front of the number
