dude can u make one that counts powers????

that wud be awesome....

[lifeg0eson666]

just use pow(base,exponent)

[sharpnova2]

@lifeg0eson666

No.

function pow(base, exponent)

{ if (exponent <= 1) return base; else return base * pow(base, exponent-1);

}

[lifeg0eson666]

@sharpnova2 Mathematically that's wrong. If you wanted pow(10,0) your "function" would return 10, where it should return 1. n^0 = 1.

[sharpnova2]

@lifeg0eson666 meant to say if (exponent == 0) return 1;

[lifeg0eson666]

@sharpnova2 Fair enough. But this tutorial is four years old, I didn't know as much as I do now.

ok first of all you don't need so many things to make a calculator.second:guys if you copy what he writes in notepad that doesn't make you a programmer.I know that my comment will be rated with "-" and so on but that's my opinion :D

[KINGV3NOM]

very nice ty but kind of hard to see(zoom in more or try another prog) and a bit difficult to understand(background)

[Newwaver2007]

Cool :D

BTW: what are the thingys you type after the add and mul?

it's a ")" and after it the screen is too blurry for me to regonise.

*Wishes you can put stuff up in HD sometime*

I am such a noob lol.

@iamanending 8 year olds don't write very good tutorials.
