Yes, 
we need this software. 
My Floating divider seems to be working now but it
needs some testing. 

I need more details on how to use this code { I do not
want to pass over teh code every time } and how to
link it to the verilog test bench

We need even more than that because the FPU is not
just the hardware but also the software library and
compiler so the testing software must cover everything

Why do you want it in C++,? C is good and even faster

What we need is to know when the exceptions are going
to happed and how do the software library "compiler"
handles it.
