- Value monitor
- more mathematical modules
my idea is mathematical Macro module with math operation matrix + - * / sin cos sqr ...... floating point value
macro module convert floating point number to moulation destinations
ideal for precision mathematical modulation 
sorry my bad english |

Sadly there are no floating point numbers in the NM or G2 at all.

why nm2 processor not support floating point ?
pc and mac cpu working floating point
gpu working floating point
creamware, uad, powercore working floating point
BIG ???????????????? |

That it is not floating point does not mean that it has no point at all - the DSP uses fixed point arithmetic.

Well, it's a matter of processor design. Both fixed point and floating point have advantages and disadvantages. Before deciding what kind of math you'll use for a certain aplication you have to weigh those.
This means the NM and G2 are very suitable for some things now and less so for others, if for example you need to work with iterative methods on very small values then the G2 is not the best system to use because that kind of thing tends to become noticably unstable on the G2 even if the mathematical expressions themselves on the surface are correct.

Some do, some don't and some use a co-processor for it, yes. Generally modern pc cpu's are very good at lots of stuff but remember that some modern cpu designs also run into trouble when processing floating point data when values get very small and they shift to a different, more acurate but slower, method of processing numbers.
General purpose CPU's are great but they aren't perfect for every aplication, if they were the G2 wouldn't exist .
As for the other systems mentioned; great, if you absolutely need floating point math then look into one of those but as Jan pointed out; you can do lots of math in a fixed point way as well, if you just need math then you'll be fine.

Should I mention all the hardware needed to support a modern computer CPU?
What I love about musical instruments is that they (fortunately most of them) don't have fans or make any noise besides what they are designed for. And of course they are much more portable and sturdy than a modern PC.
When I see my G2 I remember my old Spectrum computer ( no noise, portable, nice), but with so much power inside that I'm amazed

I've been wanting this as well - it would be nice when troubleshooting stuff like unexplainable DC buildups. I was dreaming the other day that you might be able to implement an oscilloscope as a module - so that you could get a look at the waveform before it was run through the DACs. That would be cool!
