Finally: an **emulator** (or a real machine ofcourse) to test and run your programs on.
In C64 mode, thhe compiler assumes the presence of the `Vice emulator <http://vice-emu.sourceforge.net/>`_.
If you're targeting the CommanderX16 instead, there's the `x16emu <https://github.com/commanderx16/x16-emulator>`_.
Make sure you use cx16 emulator and roms **V39 or newer**! Starting from version 6.5, prog8 targets that system version.
Your program may work on V38 but that will only be by luck.

The largest 5-byte MFLPT float that can be stored is: **1.7014118345e+38** (negative: **-1.7014118345e+38**)
.. note::
On the Commander X16, to use floating point operations, ROM bank 4 has to be enabled (BASIC).
Importing the ``floats`` library will do this for you if needed.

TODO
====
- make the floats lib set rombank 4 on cx16 and set sysinit back to rombank 0 (kernal only)
- make sure rombank is back to 4 on cx16 when program exits back to basic
- check use of float NEGOP vs NEGFAC for cx16
- allow inlining of subroutines with params
- optimize several inner loops in gfx2
- hoist all variable declarations up to the subroutine scope *before* even the constant folding takes place (to avoid undefined symbol errors when referring to a variable from another nested scope in the subroutine)
