Hi Folks,<br>
<br>
Cuis already includes Float64Array in the base image. As usual, feel
free to take the code to your preferred dialect. Primitives such
those for FloatArray would be a welcome addition!<br>
<br>
Cheers,<br>

While we're extending specialObjectsArray, it may make
sense adding <br>
FloatArray and the currently non-existent Float64Array as
well.<br>

<div>Good point. An at:[put:] primitive pair for
Float64Array makes sense too. </div>
