%

Used instead of the = key, % interprets the final operation carried out in the current calculation as follows:

  • If the final operator is + or - the second argument is interpreted as percentage of the first operand.

  • If the final operator is * divide the result of the multiplication by 100.

  • If the final operator is / give the left operand as a percentage of the right operand.

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

Examples:

150 + 50 % gives 225 (150 plus 50 percent of this amount)

42 * 3 % gives 1.26 (42 * 3 / 100)

45 / 55 % gives 81.81... (45 is 81.81.. percent of 55)
