In effect the display get the shifted by one digit to the right to overcome the overflow error
would yield those rows where Num-Coll or Num Col2 was zero, or where Num_Coll/Num_Col2 was negative, or even where the database hit an overflow error
because the ratio Num_Coll/Nura_Col2 was just too large for it to evaluate.
"Vulnerabilities in the form of buffer overflow errors
are also hard to control and predict so security solutions often interpret attacker-injected code as legitimate.
Further research inversigations are necessary, in order to analyse structure sensitivity to overflow errors
, which can occur in fixed point implementation.
