The minimum positive denormalized value in Python3.9 and up is given by math.ulp(0.0) which returns 5e-324, or 4.940656e-324 when printed with format(math.ulp(0.0), '.7').
A long time ago I read about the closest true value to zero, like zero = 0.000000001, something like that. In the article they mentioned about this value in Python and how to achieve it. Does anyone knows about this? I have look up here in SO but all the answers are about the closest value to zero of an array and that's not my point.
