[Axiom] Floating Point Math (and other stuff)

[FinaleTI]

Before a CAS could be made, the following needs to occur:
1) String -> FP number
2) FP number -> String
3) Display FP number on arbitrary display buffer at certain position (pref. #2)
4)

I have some WIP Axe code to create FP numbers from supplied ASCII strings and store them to OS vars. Currently, scientific notation support is non-existent and it only works for real numbers. I also have a WIP routine for converting FP numbers to ASCII strings for displaying, but only real numbers are supported and scientific notation support is currently iffy at best.

I have seen some AXE programmes using strings to export images or tilemaps. How is that possible?

You just have to manipulate the data correctly.  Here's the basic premise:
Set up the string.  This is done in a similar method to setting up a Picture, which I detailed here.
Then loop through the data for the sprite and convert this.  Each nibble (generally) contains one hex character (each byte contains two), so this must be converted to 0-9 or A-F.  Switch the number to its ASCII equivalent, which is shown in this chart:

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

L0 equ 030h L1 equ 031h L2 equ 032h L3 equ 033h L4 equ 034h L5 equ 035h L6 equ 036h L7 equ 037h L8 equ 038h L9 equ 039h LcapA equ 041h LcapB equ 042h LcapC equ 043h LcapD equ 044h LcapE equ 045h LcapF equ 046h

So yeah, that's the basic premise.  I hope it helps.

Bug fix! (See first post)
Also, I started creating a tutorial, so I included that too.

Update. Changes:
solve() becomes solve()ʳ
solve(x) returns a pointer to the floating-point number represented by x.
Examples:
float{solve(Select("varA"))}➔A
float{solve(solve(ᵀ+,Select("varA"),Select("varB")))}➔C

Is it just me or do the code boxes only say "array"?

[Xeda112358]

I think it depends on the browser. I am using Chrome and it works fine for me

@Taranok: Welcome here. And yea, I think it's a browser issue. Works fine in Firefox too.

[Taranok]

I'm using firefox also...  10.0.2.

The boxes still say array.

I notice your aciom use Select() command, but it's the same tokens than Axe parser command, is there no conflict?
