Re: [avr-libc-dev] libm for doubles -- how much effort is needed?

[Tobias Frost]

I saw a softfloat library using that approach. Well, that's ugly, the (user) 
application code is harder to debug. But it is supposed to work. Defintly 
another B-Plan. 

Dimitry, could you give just a rough estimation, how long it took you to 
implement the libm. (If I rememember correctly, the current solution is from 
you). A rough number is fine. Thanks!
