Constant Vector as Argument in PPL

[NumericDavid]

Hello Prime Friends,

I see a strange difference between the two PPL functions

export bla()
begin
return normalize([0,0,-1]);
end;
export blu()
begin
return normalize([0,0,1]);
end;

SIZE(bla) equals 6 and the numbers don't seem to make a sense. I'd expect bla = [0,0,-1] since normalize(v) should be v/abs(v).

blu and SIZE(blu) are [0,0,1] and 3 as expected.

Do you know what's going on?

Best Wishes,
David
