That looks neat!  Nice routine Sir!

Oh a sorting routine? Nice! This might be handy eventually if I was to work on an item menu like Illusiat 13

Draw an elliptical shape like an oval/circle

For(A,0,255
sin(A)//W->S
cos(A)//H->C
pxl-on(X+S,Y-C
End
W = Width inverse, the smaller the value, the wider the circle.  16 draws with outward radius of ~10 pixels
H = Height inverse, the smaller the value, the taller the circle.  16 draws with outward radius of ~10 pixels
A = used in for statement as the intermediate "angle"
S = intermediate sine value
C = intermediate cosine value
X = Elliptical center X
Y = Elliptical center Y

yay

funny thing is, until I wrote the routine and looked up what a sine and cosine is, I had NO IDEA what they did

I mean, I used before in Alg honors last year, but it was the last chapter for honors only, which was a crash course of trig basics

..and we just used the sin/cos functions like once and were never told what they did

257
While -1→A
Pxl-On(sin(A)//W+X,sin(A+64)//H+Y)
A
End
Even better

257
While -1→A
Pxl-On(sin()//W+X,sin(A+64)//H+Y)
A
End
I should stop.

FinaleTI was wondering how he could do some basic operations on 3-byte numbers, namely addition, subtraction, and decimal display. It took me a while to get it all working, but I wrote an Axe library to do all of the above. And while I was at it, because it would only require minor modifications to this code, I wrote a similar library to perform those three operations on 4-byte numbers. No longer shall Axe be limited to 2 bytes! (At least regarding addition, subtraction, and decimal display)

Anyways, the two libraries are very similar. They accept inputs in the form of pointers to the 3- or 4-byte numbers you want to operate on and have the same three functions:

• Addition: sub(ADD,Pointer to first argument, Pointer to second argument, Pointer to store answer to)
• Subtraction: sub(SUB, Pointer to first argument, Pointer to second argument, Pointer to store answer to)
• Decimal display: Disp Pointer to number to display sub(DEC) - Note that this does not return a string of a fixed length padded on the left with spaces like the usual Disp ►Dec. The string returned has any leading zeros clipped and consists only of the number itself.

To include the library in your program, have the library you want present on your calculator and insert a line reading ":prgmLIB3BYTE" or ":prgmLIB4BYTE" in the subroutine section of your code. The syntax for the commands is also included as comments under each function in the library source files, so you can look there if you need a refresher.


NOTE: The decimal display routine uses OP4-OP5 for scratch memory and OP6 to store the resulting string, so if you're wondering why any data you store there is mysteriously being corrupted, that's why.


EDIT: I just realized there was a slight flaw with my code. But I fixed it and reuploaded the two libraries before anyone could download them (I think). That's why the "by Runer112" is on the end of the filenames, I wasn't sure what else to add.

Yes and yes. The arguments should be pointers to where you store the values, not the actual values, because the actual values wouldn't fit in Axe's 2-byte value system. For instance, if you had a 4-byte number spanning variables A-B in memory and a 4-byte number spanning variables C-D, you could add the two values and store the result in A-B like so:
sub(ADD,°C,°A,)(Note the trick employed here. You can do this if you are adding two values and storing the result back into one of the values. Enter the pointer to the value that should serve as both an argument and the answer as the second argument and then leave the third argument blank.)

The display routines can display any number that you can fit in the 3 or 4 bytes of data: 0-16777215 for the 3-byte library and 0-4294967295 for the 4-byte library.



EDIT: Here's a little program I whipped up using the 4-byte library, showing its capabilities. It pases 65536 with ease, but unfortunately it can only go up to about 4 billion. You might recognize the pattern...
(Note that the actual routines run a lot faster than this, I manually set it to iterate only twice per second)

You can look at the source for an example of how to use the commands.
