[Jprogramming] Numerator and Denominator

[Roger Hui]

den and num illustrate different ways of computing the same thing,
hopefully in so doing improves understanding.  If you want speed 2&x: is
going to be faster.

Also, watch this:

   2 x: o. 1
1285290289249 409120605684
   x: o. 1
1285290289249r409120605684

   2 x:!.0 o. 1
884279719003555 281474976710656
   x:!.0 o. 1
884279719003555r281474976710656
