  • P%QP % Q means PP is neither greater than nor smaller than QQ (i.e., P=QP = Q)
  • P$QP $ Q means PP is neither smaller than nor equal to QQ (i.e., P>QP > Q)
  • PQP \© Q means PP is neither greater than nor equal to QQ (i.e., P<QP < Q)
  • PQP \to Q means PP is not greater than QQ (i.e., PQP \leq Q)
  • P@QP @ Q means PP is not smaller than QQ (i.e., PQP \geq Q)
