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't compare complex numbers at lib/PDL/PP.pm line 1445.
It is true that we shouldn't compare complex numbers, except for
equality, but, shouldn't the magnitude of a complex vector be a real
number instead of a complex number (with zero imaginary part)?
I tried to fix it by replacing the qualifier 'float+' in the pp_def of
magnover in Ufunc.pd by the qualifier 'real', but then the tests fail
as bytes are not converted to floats.
Best regards,
Luis
