Vectorial Math
« on: December 21, 2014, 08:04:35 pm »
Ever dreamed about being able to do vectorial math on your z80 calculator? Well, I started making an app for that!
So far it only features the scalar (dot) product, lol. You can switch between the different product types by hitting the multiply key multiple times.

So that's what this all was for :D I really have no clue what vectorial math is, though.

Btw, should this be in the asm subforum or the z80 projects forum?

Is this a parser hook?

So vectorial math alternates between multiplication and addition? (I've never heard of it either). Anyhow, it's always nice to see new math programs. :)

Lol, there's the dot product and the cross product as 'main' things, i guess.
I already added both, then I also added getting the length of a vector and 'normalizing' a vector, so scaling it down to the length of 1

Right now I'm trying around on making a custom menu when hitting STAT twice

Could you make another alpha-F? menu also/instead?

Yeah I thought about making also such input fields on MP calcs. Depending on how complex it'll be

Soooo I got a little issue with pasting characters - inside of the TIOS text edtior.
well, the result is looking like this:


My insert token routine is this:
Code: [Select]
insertTok:
; hl - tok
; bc - len (bytes)
   push bc
      ld de,appBackUpScreen
      ldir
   pop bc
   ld hl,appBackUpScreen
   ld (rclQueue),hl
   add hl,bc
   ld (rclQueueEnd),hl
   set 7, (iy+0Eh)
   set 2, (iy+33h)
   ret
Any help would be awesome ^.^
