== definition of even & odd numbers ==
This may be frivolous/trivial, but since the task is to determine if an integer is odd or even, a simple definition of an odd/even number could be in order.
<br><br>From MathWorld:▼
<br><br>An odd number is an integer of the form n=2k+1 where k is an integer.▼
<br><br>Integers which are not odd are called even.▼
<br><br>The above definition has the advantage that it isn't dependent upon its (say, internal binary) representation (or any base, for that matter), although that is one method to determine evenness/oddness. ▼
<br><br>I've also seen the definition that an odd number is an integer, that when divided by two, the absolute value of the remainder is (positive) unity.▼
▲
<br>An even number ... the remainder is zero.▼
