Re: Odd Complex behavior

That sounds like a recipe for even more confusion further down the road; now whether you get a -0-i or a 0-i out of your bag depends on which one of the two was put in first, and the difference between 0 and -0 surely makes a difference in enough cases when doing floating point math that it wou

Re: Odd Complex behavior

We could potentially give 0e0 and -0e0 the same .WHICH, which would solve the bag issue. > On 13 Jun 2019, at 21:02, Timo Paulssen wrote: > > Unfortunately, that's what the IEEE prescribes, so all we can really do is: > *shrug* > > On 13/06/2019 21:01, Sean McAfee wrote: >> On Thu, Jun 13, 20

Re: Odd Complex behavior

Unfortunately, that's what the IEEE prescribes, so all we can really do is: *shrug* On 13/06/2019 21:01, Sean McAfee wrote: On Thu, Jun 13, 2019 at 11:12 AM Brad Gilbert > wrote:     > (-i).reals     (-0 -1) Ah, so it's nothing particular to Complex: > bag

> bag i, 2i - i bag(0+1i(2)) Well and good. > bag -i, -2i + i bag(0-1i, -0-1i) Huh? But this works as expected: > bag Complex.new(0, -1), Complex.new(0, -2) + Complex.new(0, 1) bag(0-1i(2)) Is this a bug, or is there a sense in which it's correct?
