Hi mittyri,
Nope. 0 is by definition neither positive nor negative.*
❝ A question:
❝ is 0 a positive endpoint?
Nope. 0 is by definition neither positive nor negative.*
sgn(x < 0) = –1
sgn(x = 0) = 0
sgn(x > 0) = +1
x = sgn(x)·|x|
Logarithms are defined only for ℝ>0.- The weird ISO 8601 mandates ‘+’ for 0. Treating zero in computation is yet another story.
