thanks Pat. I know fixed point can often be sufficient but my
intention was to run gnuplot to process my data into svg and serve it
up with apache since I already have this coded.
gnuplot requires fp.
Now if I could install softfloat without too much pain this would be
a good option.
The other route is to dump what I've got and find another way to do
LR curve fitting, replace simple log expressions with a whole bunch
of lookup tables, do some complicated preprocessing and then code the
plotting routines using something like GD.
Using the 30 or so lines of code that I already have to do all this
with one gnuplot file also appeals.
So my basic question remains:
What is needed to have floating point capabilities on 7250?
