RE: New firmware for the Swissmicros DM15L
Here's another beta with:

1. sin(180) is fixed properly Smile it only took implementing sinpi() from scratch lol
2. With the new sinpi() available, I was able to fix the behavior of the complex power function cpow(), the one behind Y^X. It now handles cubes of negatives correctly and it fixes the bug that John found as well.
3. There is now a space between mantissa and the exponent, improving readability. Thanks for pointing that out Jean-Charles!

This one has to do with subnormal numbers and is not fixed. My own naive implementation of printf is getting too complex to debug and I will re-implement it by copying what people did in the actual printf source code, so this will be fixed then.

That sounds interesting, I added it to the list and once everything else is done I might give it a go if there is room left Smile

Added to the list as well, thanks!
