[PD-dev] I am really confused by this C problem - help?

[federico]

float (t_float) and int (wich you specified with %d) have an
incompatible bit arrangement.

so it is wrong doing:

    t_float x = 8.0;
    post("%d", x);

you surely will get an inconsistent result.
better you do an explicit cast:

    post("%d", (int)x);
