Hey, I'm about to package the library for inclusion in Void Linux so I'd like to ask you to tag a version in Github. I see in the version file the current one is 0.1.5 but it simplifies our process and discussion greatly if there is a Github tagged versin :)
Thanks!
There is a bug in defun discrete-bezier-curve
.
Sometimes it calls (atan 0.0 0.0)
, spec [1] specifies that:
If both are supplied, number2 can be zero provided number1 is not zero.
The problem is fixed using a safe version of atan:
(safe-atan (x y)
(if (and (= x 0) (= y 0))
0
(atan x y)))
I'm not sure if "0" is the correct answer.
Regards,
Alessandro
Is use of
I think it's the cause of warnings I see like those below.
I think it could be fixed by putting a real version x.y thingee with numbers in there instead. Presumably the version from the file named VERSION, but I don't know.
We are hoping to not have to see all these warnings every compile.
Thank you,
Mark
