human vs computer calculator is that even a battle :)

I fear when it comes to calculations with percentage the main problem are users that don't know how to enter the formula right.

My math teacher always said: NEVER use the percent and the root keys of your calculator because they will only cause trouble. Do your calculations the "real" way (x/100*y) instead of percent and (x^(1/y)) instead of root.
It seems he was right :rolleyes:

I don't see what's wrong with that. The way the computer interprets your command is 100 minus 15 percent of 1 which is 100-0.15=99.85. I assume you want to subtract 15% of 100 to get 100-15=85? Basically the % operation just divides the value by 100. So 15/100=0.15. You still have to multiply that by something (in your case 100) to get back to the percentage of the value you want.
