I was assuming that any of add or subtract positive or negative zero, or multiply or divide by 1.0 would do the trick. Why wouldn't this be<br>
adequate?<br>

I think "x + 0.0" is adequate, but unnatural. It reminds me of javascript's typecast hacks.<br>

Ah, I see. Hang on. There is no support for SmallFloat64 on 32-bit Spur.<br>
Only in a 64-bit image/on a 64-bit Spur VM will you be able to create<br>
instances of SmallFloat64. And so far I only have this working in the VM<br>
simulator. I've yet to try and create a real VM, and even then it will<br>
only be a Stack VM.<br>

Wouldn't it be possible to support them in a 32-bit VM? Aren't object headers the same in both VMs? Or is it because of the difference in alignment?<span class="HOEnZb"><font color="#888888"><br>
