It turns out I did over-engineer the solution somewhat - this version is
far more efficient, honours NaNs and triggers SIGFPE if infinity is passed
in (subsd triggers it), hence there are no regressions.
function fpc_frac_real(d: ValReal): ValReal; compilerproc; assembler;
nostackframe;
Hi all,
I've the web-client for managing fppkg-packages in a web client running.
I've added some packages and will add some more in the future.
It is possible to add your own packages if you want to, if you want to
try, please contact me. I'll explain how to do so.
If you want to use the fp

The code also has to work if exceptions are disabled.

As Sven pointed out, there are still
faults in our functions in that they don't
honour NaNs. It's an easy enough fix, but
will just need an extra bit of code.

I reopened the bug ticket to attach a patch with the new function. It also
contains some code for "Int" that passes through the input unchanged if its
magnitude is greater than 2^52 (at this point, the precision means it can't
have a fractional component). I've set it to "feedback" currently so S
