Math functions
« on: February 09, 2011, 03:26:01 pm »
If you would like to see non-math related things, like string operations, just mention them...

...Unless it involves division by 0. I don't want to create a wormhole in my Prizm.  :P

I haven't a clue what RNG is...

Oh, wait, that's Random Number Generator, isn't it?

Quite right!  Although now that I think about it, the secure one would be kinda cool, too.

Calculus is very important.

Yeah, but I'm not sure how you pass a function to another function in an assembly program.

You just leave the result either in a register or in memory and then the next function uses that. I imagine that you could set up a spot in RAM that holds the address of where the arguments are, but that isn't very useful. Also, I don't know how the stack works on the Prizm, but if it doesn't push PC onto the stack when you use CALL, then you could pass arguments through the stack.

It pushes PC and SR onto the stack, so I'd have to pop those and repush them afterwards.

Eww, I don't like that because sometimes I forget and then I crash my calc :(

I'm not sure what happens if I screw up the stack on my Prizm. I've never used it. Let's try it  >:D

Take photos, I wanna see if it goes boom.

edit: oh wait, that only happens if you manage to divide by zero successfully...

I am confused as to which place these math functions are going to be added?  There really isn't anything explaining O.o

right, but for which purpose?  Just math in general?
