But does that really help if the value being printed comes from a single precision "float"? I guess what I'm asking does Gnuplot use "double" floating point thoughout the SPLOT contour calculation and its printing to the TABLE?
gnuplot has been using double precison fp math since some time in
the last century I think.
If the contour calculation doesnt, that would constitute a bug. Do
you have evidence for that?
There is one exception that I know of.
If a binary matrix is read in, it is stored as (float) rather than (double). There's no good reason for that, but the binary input code is quite tangled
so fixing it would require some disentangling. It would be a good project
for someone (hint hint).
