[1.0] Calculator

[Alex]

YESH CALCULATOR still going to divide by 0

[saab900]

Nurta, you should program something really wierd to happen if you divide by 0, like flash 100 pics in 1 sec or make a wormhole thingy, that would be sweet!

This is good, but for the next release, I have some ideas:

A ^ button for doing exponents
Making a shortcut to = with like, play/pause or something
Have the back button be the delete or clear (when tapped, it doesn't exit the app)
Perhaps cos, sin, and tan?
( and ) (I mean the parentheses)
etc., etc.
Thank you for making this, but I don't think I will use it very often, because I have Alg. II and then Pre Calc next year, and this is really basic.

Which file do I open? This looks different than most of the other games.
Edit: Nm, forgot to extract.

[collver]

have a graphic pop that call the user a noob, should they type in 3x5 or other insanely easy problems.
for example

The new version is much better, well done!
In the future maybe you can decrease lag and the highlighted buttons.
I also agree that when someone tried to divide by zero a wormhole is created showing the credits.

doable

it already is

Have the back button be the delete or clear (when tapped, it doesn't exit the app)

yeah, jsut have to figure out how to do it exactly

Perhaps cos, sin, and tan?

do-able, I'll probably add in a menus system (constants, trig, exponents, etc)

( and ) (I mean the parentheses)
etc., etc.

That's a little more work, I'd have to put in order of ops and stuff

Although I already have a system for this in Java, C# isn't too different, maybe I can copy paste and modify significantly

the lag is actually programmed in, since at first you'd hit right and it would go right 5 times even if you do it fast. I'll play with the numbers some

            if (gps.Buttons.Back == ButtonState.Pressed)
                this.Exit();

yeah, that says if the button is pressed exit, it doesn't say if button is held for X seconds exit but if for less than that, backspace

I'll probably just have it if button is pressed, start timer while(button is pressed) do nothing, on un pressing end timer, if timer.time>X do this, otherwise do this.

I knew I'd have to do it there, I'm not an idiot, just have to look up the easiest way to do a timer and stuff.

Thanks Nurta!
Rep for you!

Here's a skin I made for the calculator. Download the two images below (right click and save as) and replace them with the two image files of the same name found in the content folder.

calc shell.png:


blank.png:
<--there is an image there

I can do other colors by request.

[charmed61]

can u make a blue one? thanks

[bjmiller121]

Here you go charmed:



you'll have to rename the file to "calc shell" and use the same blank.png as above.

Theres an easy way to have it only do the button action once.

Declare a boolean and set it to false

bool i = false;

then when you have this code

if (GamePad.GetState(PlayerIndex.One).DPad.**** == buttonState.Pressed)

change it to

if (!i && GamePad.GetState(PlayerIndex.One).DPad.**** == buttonState.Pressed)

Then in the same block of code add

i = true;

and lastly make another block of code for

if (GamePad.GetState(PlayerIndex.One).DPad.**** == buttonState.Released)

and add this in that block of code

i = false;

[Nurta]

That's clever, good idea.

[LedZepp]

Yea im in the process of making solitaire and i was stumped for an hour trying to figure out how to only make it move 1 space instead of a random number

[egamerhdk]

So far so good...

[luinfana]

Here's another skin...



(save as "calc shell.png")



(save as "GameThumbnail.png")

<- save as "blank.png"

Enjoy!

[retrac1324]

Thanks for the fully functional app, and thanks luinfana for the nice backgrounds (the black one is especially nice)

[templar]

if your looking for an easy way to make a calculator the best advice i can give is take a look at the shunting yard algorithm (check wiki)

this is a infix to postfix converter (which should be about 30 lines of code if done properly with functions), its just a matter of setting up operand precdence as well having good knowledge on stacks and knowning when to push and when to pop. once you have it in postfix, a simple postfix parser can easily compute the equation. the beauty with SYA algorithm once you convert, order of operators is basically removed and so are brackets,

cheers
