[Octave-bug-tracker] [bug #54622] test importdata fails in dev octave with windows

[Dan Sebald]

Follow-up Comment #31, bug #54622 (project octave):

Oh yeah, that's right.  Well, actually looking at the result you posted, it
suggests two conflated issues.  Note how dlmread() doesn't quite provide the
whole interpretation:


data = dlmread ('test.txt', '\t', 0, 0, "emptyvalue", NA);

returns

3.1000 Inf NA
-Inf NA 128.0000 


The NaN is not processed as expected upon success in

"NA".https://savannah.gnu.org/bugs/index.php?54622#comment5

According to the link

https://stackoverflow.com/questions/1923837/how-to-use-nan-and-inf-in-c

this particular compiler/library must have support for INFINITY then, but not
NAN.

Something about the mode when opening or some directive about how escape
sequences are treated.  Hmm.
