This may be frivolous/trivial, but since the task is to determine if
<br><br>From MathWorld:▼
The definition (below) defines an ODD NUMBER, and goes further than limiting the definition to an ODD INTEGER:
<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. [[User:Gerard Schildberger|Gerard Schildberger]] 00:46, 16 March 2012 (UTC)▼

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>For an even number ... the remainder is zero.

This very short solution works only for Bin Fixed(n,0) variables.
Well i is Bin Fixed(15) by default.
consider also Dec Fixed, Float, and Pic variables
where mod(v,2)=0 -> v is even (if it's an integer)
