- The function of the % key is similar to the one found on some CASIO calculators:

- If the final operator is + give the percentage increase the result is over the second operand.

- If the final operator is - give the percentage decrease the result is over the second operand.

- If the final operator is * give the right operand as a percentage of the left operand.

- If the final operator is / or Mod, give the left operand as a percentage of the right operand.

- If the final operator is x**y give the left operand raised to the power of the (right operand / 100).

- In all other cases the % key gives identical results to the = key.
