Subject: JavaScript test for even or odd number


| Now I'm no programmer ....... but I'm developing a JavaScript application
| that requires a numerical value to be tested to determine if it's even or
| odd. I figured that the simplest way of doing this was to convert the
value
| to binary, eg:
|
| function number_check(value) {
|  var binary = value.toString(2);
|  if (binary.charAt(binary.length - 1) == "1") {
|   return false;
|  }
|  else {
|   return true;
|  }
| }
|
| I'd be interested to hear from anyone who can offer alternative solutions.
|
| TIA
