modulo

pseudocode:

if number % 2 == 0
  return "number is even" (is_num_even = 1 or true)
else
  return "number is odd" (is_num_even = 0 or false)

plus you'd want an input validation beforehand

who needs modulo when you can get less characters out of

while (number > 1) {
  number -= 2;
}
return number;

very efficient

edit: or theres the trusty iseven api

here is somewhat less:

return (number % 2) == 0;

return !(number & 1);

#You are an input. You have value! You matter!
if&nbsp;number&nbsp;%&nbsp;2&nbsp;==&nbsp;0
&nbsp;&nbsp;return&nbsp;"number&nbsp;is&nbsp;even"&nbsp;(is_num_even&nbsp;=&nbsp;1&nbsp;or&nbsp;true)
else
&nbsp;&nbsp;return&nbsp;"number&nbsp;is&nbsp;odd"&nbsp;(is_num_even&nbsp;=&nbsp;0&nbsp;or&nbsp;false)

Am I doing it right? /S.

Don't put nbsps in code blocks, they show up literally.
