Hi Luis,
I'm not a PDL expert, just a hobbyist. In my understanding, reducing
the set of GenericTypes will limit the generated type-loop to this set
and will cause any input arguments outside of this type set to be
converted first. This would mean that a large integer vector will be
con
Hi Jörg,
Thanks. It does work. I have a question: if the input is some large
vector of some kind of integers, is it first converted to a float
vector with this solution? Should the possible space wasted be a
concern?
Regards,
Luis

Hello Luis,
probably this does the trick:
pp_def('magnover',
HandleBad => 1,
Pars => "a(n); real [o]b();",
GenericTypes => [qw(H C G E D F)],
Then in t/ufunc.t (line 106) the expected type just needs to be
changed from 'cdouble' to 'double'.
Integer types will be promoted to float an

I believe there are good reasons for the qu
Hello Luis,
the results look fine when the expected types in the two failing tests
are adjusted. Don't know if it would break any "real" code, maybe
"is_pdl" is just too strict here.
t/ufunc.t:
is_pdl $empty->magnover, sbyte('BAD'), "bad flag gets set on empty magnover";
is_pdl +(sequence(4
Hello,
In some of my programs I used the code such as
$abs=$cvec->abs2->sumover->sqrt;
to get the magnitude of a vector $cvec. I just replaced it to the cleaner
$abs=$cvec->magnover;
But then my program failed when I made the comparison
if($abs > 0){...}
with the message
Can'
