I'd suggest checking for trunc with Autoconf, then providing an
implementation based on floor if it doesn't exist, i.e. something
like this:
#ifndef HAVE_TRUNC
double
trunc (double d)
{
return d >= 0.0 ? floor (d) : -floor (-d);
}
#endif
I do something like this for the "round" function.
That's a good idea. Maybe we should gather these sort of functions
into a common module and put it in libpspp and/or offer it to the
gnulib developers for inclusion there.
