Xcalc is a fairly basic calculator that allows mathmatical equations to be entered via the console
or by using the GUI calculator interface.
Xcalc is based off of QuickCalc by Mark Ribau. A good portion of the code has been rewritten, and
the GUI has been completely rewritten.
Installation
------------------
Extract the zip and put the xcalc folder into
\World of Warcraft\Interface\AddOns
**WARNING**
xcalc 2.0 files have changed and any previous version needs to be deleted before. ie. dont copy
this over 1.0 installation.
there is a = minimap icon that will all open the GUI interface.
also of importance xcalc will rebind your all your numberpad keys to the gui interface when the Gui
is open so it is not necessary to bind those keys. the GUI will rebind the numberpad keys back to
their original bindings when the window closes. With the GUI open use shift+enter to open the chat
dialog, and you can shift+left click on the number window to output that to the chat dialog if it is
open.
Xcalc does support computing of expressions from the command line. This is accessed by using the
slash commands with the expression after the slash command.
Math operators:
+ - * / ^ ( )
Special Keyword:
ans -- Will return the last answer given from using the slash commands
Math Functions:
abs() acos() asin() atan() atan2(,) ceil() deg() floor() frexp() ldexp() exp() log() log10() min([,...])
max([,...]) mod(,) rad() random([[,] ]) randomseed() sqrt() cos() sin() tan()
Please see http://www.wowwiki.com/World_of_Warcraft_API#Math_Functions for more information on the math functions.

Optional Files - Xcalc
Sorry, there are currently no optional files available.
i have the latest version and i was getting hit with an error if i would try to do multiple calculations in a row. EG: 2+2+3=7 2+ERROR.
Changing lines 377-378 to the following fixed this problem and made the mod act like a normal calculator or like the calc program that comes with windows. This fix should be incorperated into the actual mod. If there is a better fix, feel free to do it. However, without this the mod is only good for 1 calc at a time unless you hit the clear button in between every calculation that you do.
Code:
function xcalc_numkey(key)
if XCALC_PREVIOUSOP == "=" then
xcalc_clear()
end
local currText = XCALC_NUMBERDISPLAY;
I would also suggest changing the binding to close the Xcalc window with one that toggles it. eg replace the XC_CLOSE binding with this one
Originally posted by lycanther There are lots of programs that can correctly handle complicated unit calculations (for example, type 2 ft * 3 m into google and it will return 1.8288 m^2). The dimensionally correct result would be
4g*20s = 400s*20s = 8000s^2 = 0.8g^2
and it should be reasonably easy to implement this in a domain where there's only 1 dimension...but why bother? I can't imagine any reason why anyone would ever multiply two amounts of money. Probably 4g*20s should just return "User error! WTF were you thinking?"
I like that "User error! WTF were you thinking?"
I should set it up to make the check and not allow multiplication or division with money and money... Just this hasn't been one of my bigger priority programs of late. (inadvertently the reason why I haven't been updating it very much)
Originally posted by moird it is like that, because 100 copper = 1 silver and 100 silver = 1 gold
so technically speaking the calculator is performing the calculation properly.
because 400*20 = 8000
and in reality, I could program a check into the calculator to prevent such calculations from being performed in the first place, but haven't gotten around to it yet...

That is how it is suppose to function and how it has functioned... if I have some more time I will look into it.

Isn't there any way to make the keybinds be used for the calc when it's open, and for my normal functions when it's closed?

i rather doubt that ... (and ull learned at school that units on each side of an equation must be the same ..)
(and i dont want to trade with ppl ingame that rely on such stuff:P)

Wrong. "...I triple-checked the edits.". If other things were modified, I would have mentioned them. Mentioning errors without mentioning all changes made to the mod is unprofessional, thus it was not done. And others enjoy testing mods in a rigorous fashion, irregardless if they actually need to or not.

Never said it was "author coding preference". The point of the post was to provide testing feedback on specific coding suggestions made by someone else. Irregardless of whether said changes are (in either theory or common practice) the right thing to do or not.

And I merely pointed out--after thorough testing I had done after making the exact changes suggested--that there was a problem with the mod after those changes were implemented on my local copy. A problem which prevented the mod from being accessed. And I provided full details. So I don't really see what the issue is here .
The updated Xcalc 2.03 works without problems/errors so far here as well.

That the mod author will make the changes HE finds beneficial to his mod is kinda self-evident.

(I find it preferable to the usual all inclusive comment which is "this mod doesn't work"
even when further investigation reveals that it was suffering a minor issue)
2.03 works error-free "out ot the box" for me, thanks for the update
Dridzt's suggested changes to v2.01 don't work and create errors at logon, causing the mod to die. Recommend doing your own coding, moird, to make sure things work well before updating this great mod .
Did the suggested change at line 141, which is replace: xcalc_minimapbutton_updateposition();
with:
if (xcalc_minimap_button) then
xcalc_minimapbutton_updateposition();
else
xcalc_minimap_init();
end
And also replaced instances of math.mod with math.fmod on the following lines: 511, 515, 521, 525, 530 & 533.
Doing the above creates the following errors at logon and the mod doesn't load:
"xcalc\\xcalc.lua:281: '=' expected near '?'"
"<string>:\"xcalc_core:OnEvent\":1: attempt to call global 'xcalc_initialize' (a nil value)"
Of course, I triple-checked the edits. And did it with WoW exited as opposed to doing it in-game then reloading the UI. Without these changes (using the original v2.01 files), no errors and no large problems here so far.
