[QUOTE=nullsquared;22086309]Try -2^-2 and -2^--2.[/QUOTE]

Whoops, my expression parser used to get 3 for both :S
now:

Hook Main( )
    Print( -2^-2 )
    Print( -2^2 )
EndHook

I'm not working on some boring parser... I'm working on a physics based racing game!

Only had to adjust one line and a small helper-class :)
I'm going to contact the author of this program about it.

Not me... :'([/QUOTE]

I wish there was a sympathy rating :(

I don't think the author is around anymore, since the official website is down and he didn't respond to an e-mail I sent him a few months ago.

I must say, you've really nailed performance already.

me neither :keke:

I'm still working on [url=http://www.moddb.com/games/rotion]this[/url] game, although I haven't released any media for quite some time. I hope to have a big update somewhere in the next few days, although uploading a video could prove problematic due to bandwidth restrictions :(

Nice :smile: Does it handle -2^--2 (double negation) correctly? :v:

Whoops, I had it outputting what it parsed the code as after splitting it up into tokens and simplifying it, the actual code I fed it was:

Hook Main()

	Print( -2^-2 )
	Print( -2^--2 )
	
EndHook

Wait, it's evaluating -2^2 as -4?

Am I the only person who thinks something is wrong here, or have I been lied to since third grade?

[QUOTE=GreyIOutcast;22092164]Wait, it's evaluating -2^2 as -4?

It's doing -(2^2), not (-2)^2

[nullsquared]

[QUOTE=GreyIOutcast;22092164]Wait, it's evaluating -2^2 as -4[/QUOTE]

-2^2 is the same thing as -1 * 2^2

[tehbiga]

[QUOTE=nullsquared;22092729]-2^2 is the same thing as -1 * 2^2[/QUOTE]

Try (-2)^2 :D

setting up box2d and creating a few shapes with velocity isn't boring?

[turb_]

[QUOTE=Overv;22083959]Currently this is the interface to add constants and functions:
[cpp]// Set constants
expression.SetConstant( "pi", 3.1415926535897932384626433 );
expression.SetConstant( "e", 2.7182818284590452353602874 );
expression.SetConstant( "phi", 1.6180339887498948482045868 );

// Add functions
expression.SetFunction( "sin", Math.Sin );
expression.SetFunction( "cos", Math.Cos );
expression.SetFunction( "tan", Math.Tan );
expression.SetFunction( "log", Math.Log10 );
expression.SetFunction( "ln", Math.Log );
expression.SetFunction( "sqrt", Math.Sqrt );[/cpp][/QUOTE]

Doesn't look like an interface to me :p

Also, why not do this:
[cpp]
foreach(var kv in new Dictionary<string, double> {
{ "pi", Math.PI },
{ "e", Math.E },
{ "phi", 1.6180339887498948482045868 },
})
expression.SetConstant(kv.Key, kv.Value);
[/cpp]

Yeah that's boring as hell, except that was angular velocity. Which is waaaaay more awesome.

[QUOTE=nullsquared;22092729]-2^2 is the same thing as -1 * 2^2[/QUOTE]

Actually, it's not. -x^2 is the same as x^2, the result will always be positive.

[ThePuska]

[QUOTE=DrLuke;22101623]Actually, it's not. -x^2 is the same as x^2, the result will always be positive.[/QUOTE]

ax^2 = a(x^2)
(ax)^2 = a^2*x^2

-x^2 = -(x^2)
(-x)^2 = (-1)^2*x^2 = x^2

[Robert64]

[QUOTE=TehBigA;22095257]Try (-2)^2 :D[/QUOTE]

Hook Main()
	Print( (-2)^2 )
EndHook

Output: 4

Can anyone give some complicated ones which will test that I have operator preference right? stuff like -2^--2 etc.

Before you argue about math-related topics, please go review your math skills :downs:

Exponentiation has a higher precedence than negation.

Ugh, why the f*** does Love2D.org go offline every time I want to continue working on my game. Is there some way to download their entire wiki with API reference? I really need offline documentation.

You can download an entire wiki, but it's messy business, and takes up loads of space.

I bet Love2D has downloadable documentation anyway though

[Boris-B]

I've got some progress done.

I formatted all the information I got and pulled all the info I need out of the shoutbox.

Square you, I am used to write x² and then -x² would mean that it's (-x)^2.

[nullsquared]

-x² is still -(x^2). Only (-x)² is (-x)^2. Whether you write ² or ^2 doesn't matter - you need the parenthesis.

What? My graphics calculator does exactly what nullsquared is saying.
