Using Numbers toString() method in radix mode

When using Number's toString() method in radix mode, it is possible to output the number using a different base, such as 2 for binary, 8 for octal, or 16 for hexadecimal. This functionality is useful for dealing with numbers in HTML. HTML uses hexadecimal representations for each color. var iNum = 10; alert(iNum1.toString(2)); alert(iNum1.toString(8)); alert(iNum1.toString(16));
