 ### WANTED
 
 - For the time being, i will not look at writing IEEE754 functions in assembly.
   Please see below for more info on what is needed to do this, should you be
   interested in doing this. Please contact me before you are putting work into
-  this, so we can discuss some things and prevent anyone wasting time.
+  this, so we can discuss some things and prevent anyone wasting time :)
 - It might be possible to produce a similar kernal- or OS- wrapper override file
   as the C64 one for other targets (or port the C64 one to other CBM targets).
   - If you create a new one, keep in mind that the compiler *right now* will
     currently work with IEEE754 floats, which your library calls must also work
     with (which will involve converting forth and back to whatever other format
     at runtime), and there is no easy way tp change that.

 - Find some more generic math functions that we can use in softmath
 - When all obvious tests have been created and work OK, we can merge
+  - for the failing tests, create "negative" cases
 
 After the merge, the following things can be done more or less independent from
 each other (not necessarily by me :)):
