Not the OS, but a special CPU instruction: isX86_64() in

Is there a way to separately stringify/print the mantissa and
exponent of a floating point?
I want this in my pretty-printing module to produce something like
1.2 \cdot 10^3
instead of
1.2e3
I could of course always split on the e but that is kind of
non-elegant, I believe.

but there is ARM64 coming. and gdc, for example, will has no problems
to support it out of the box due to using gcc cogegen.
Just for a bit a fun i've implemented a simple doubly linked list
and trying out some range based stuff. Whilst doing so i have
some questions which you guys might be able to answer.

implementation fails. I've put assumptions: is it right ?
