Floating points accept +0.0 and -0.0, but these numbers behave the same in almost all operations (+0.0 == -0.0 for example). AFAIK the only different thing is that 1/+0.0 == +infinity while 1/-0.0 == -infinity. You may care about that as a programmer writing very tricky programs with floating point numbers, but as a darktable user, they are just the same! -- Matthieu Moy https://matthieu-moy.fr/ ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to darktable-dev+unsubscr...@lists.darktable.org
