Does anyone know how I can create a formula to calculate this: x^y (x to the power of y)? I need it to be capable with y not being an integer (e.g. 1.234).

I am limited to these functions:

- Multiplication, subtraction, addition and division.
- Powers with positive integers only as the little-number-thing.
- Square roots (with the %sqrt( ) function).
- Other zMUD functions.

Even if you don't know zMUD, any formulas or anything would be helpful. And once I can get this, I'll also be able to find out how to root with non-integers as well.

Thanks.

do this....

%launchprogram(c:\\windows\\calculator.exe)

I need it to create custom functions though.

what are you doing anyways?

Math?
Word wrap?
Are you using zmud to be your OS?

Heheh, pretty much the latter.

I know that what I'm asking is possible, whether it is half a line long or 5000 lines long...

Everything you wanted to know about functions but where afraid to do a google search on.

Been a long time since math theory, but doesn't every advance math function break down to addition and subtraction?

Here's something I found for doing powers:

Hmm...

Hopefully... I just need to find the formulas for them like that.

The link I gave you goes down into basic math fuctions if you click enough.


edit: HA the site you showed has a link to the site I showed


edit 2: Ok so I looked into it a bit, and it seems your going to need to use logs and exponants. The site also has the formulas for logs and exponents, which will probably use some other fuction that you will have to look into.

Amazing what our brains can do.

z=@x
#loop (%abs(@y)-1) {#math z @z*@x}
#if (@y<0) {#math z 1/@z}

That's a simple solution for integers, but Zmud script alone isn't capable of doing noninteger powers that I know of, and why you would ever want to do that is beyond me.

You could write a COM component and call it in zMUD, but that's the only way I could think of to do this. Did you ever think that maybe this word wrapping thing isn't really worth it? I mean, isn't zMUD slow enough already? Heh heh...

What has this got to do with word wrapping? I already have made (after lots of zMUD crashes) a wrapping function which works, bug-free to my knowledge, and customizeable.

I think it is completely possible.

Logs are a variation on summation. So you need only to create either a log table, or a really cool loop.

And for decimals, merely convert that decimal into a fraction and the site I gave you will show you the rest.

I don't really want to enter in the entire logarithm/antilogarithm table(s) into zMUD script...

But how would you convert decimals like pi into a decimal? I suppose you could round it , for example:

3.4690308290374 = 3 4690308290374/10000000000000

(I know that that number isn't pi, but I forgot the decimals after the first four-ish places in pi, so I just made a random number. )

Pi is a ratio that is converted into decimal form. So for pi, you would just use the original formual.

But it should not be that hard to turn a decimal into a fraction. I'm not a mathmatician but I remember being asked to do that in 8th grade.

There is no reason to work beyond the 4th decimal place unless your doing astronomy or building something that needs to keep people alive.

Also, I'm sure your method will work... remember, computers don't really care how many times you do the loop.

They do sometimes...

When you do a loop 2^512 times, then your doing something wrong.

Erm, didn't Zmud allow you to use vbscript/jscript inline? I think I saw some scripts that accessed jscript through some "%something" syntax. If you manage to find out what it is then in Jscript the functions are:

Math.pow(base, exponent) - Returns the value of a base expression taken to a specified power.

Math.sqrt(number) - Returns the square root of a number.

Math.log(number) - The return value is the natural logarithm of number. The base is e.

Math.exp(number) - The return value is enumber. The constant e is Euler's constant, approximately equal to 2.178 and number is the supplied argument.

Plus there are all the derived math functions (sine, cosine, etc), and most other stuff.

And why you would want to convert a float into a ratio of integers is simply beyond me.

ooh forgot about that. Yeah next to reg expressions, is a button that lets you run a vb script.

The reason for turning them into a ratio of integers isbecause the website tells you how to handle those, but not decimials
