When is the value Zero negative or positive?

OTG-467455Nov 13 2017 — edited Nov 23 2017

Examining the savings account and checking account code one sees that only values greater than zero are treated as positive values.

This made me think about the value ZERO.  In mathematics and physics, when is ZERO a negative value, when is it a positive value, is it a sign itself or is it unsigned?
