%

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:
gives`150 + 50 %`

*225*(150 plus 50 percent of this amount)gives`42 * 3 %`

*1.26*(42 * 3 / 100)gives`45 / 55 %`

*81.81...*(45 is 81.81.. percent of 55)
