Re: NIOS and ftoa()
John Speth - 2009-11-18 17:43:00
(I'm to OP)
Thanks for all the good suggestions that have come forth so far. Some will
be useful and some won't be. I can envision considerable execution savings
if I use some sort of fixed point math and special-purpose custom formatting
instead of using the standard C library functions ...

I am just wondering if you could give some codes regarding the operation of
