When the accessor functions for a class are in a different package, is there a shorter way than the 2-symbols-version of WITH-ACCESSORS to map them to symbols in the local package?

please I've got this error quickloading iolib/syscalls on armhf: ondition of type: SIMPLE-ERROR

[22:30:34] <Posterdati> `(VECTOR ,SI::ELT-TYPE (,LENGTH)) is not a valid type specifier.

the funny thing is that I have another raspberry pi 3 with a cloned sdcard wich works

Has anyone delt with float length limitations on FLOOR and CEILING? For instance (= (ceiling 111.000001) (floor 111.000001)). Using SBCL "1.3.19.122-3383977aa" on a x86_64 linux install.

ejohnson: that sounds like general floating-point-ness than anything to do with floor and ceiling particularly

Yes, very exciting. We have the #clim IRC channel now and jackdaniel is going a great job with maintaining it.

ejohnson: Yes, and I am working on Second Climacs, which will have much better support for editing Common Lisp code.

Bike: I'm trying to write something a little more flexible than typed information. I actually have an solution that avoids the whole floor/ceiling thing. Thanks for the suggestion though.

ejohnson: It is entirely possible that the last digit disappears when such a number is read using a float format with not enough precision.

It just so happens that 111.0 is the closest possible approximation in single-float precision of 111.000001.

ejohnson: If you do (= (ceiling 111.000001d0) (floor 111.000001d0)) instead, your problem goes away.

For the people here with long-term memory problems, ejohnson worked on (first) Climacs and Drei.

ejohnson: Since you were active here, ELS (the European Lisp Symposium) has become a successful annual event with almost 100 participants each year.

ejohnson: The number of paper submissions has also increased over the years, improving overall quality. Next year, it will be in Marbella in Spain, where Ravenpack has its headquarters.

ejohnson: But I generally hardcode f0 and d0 when I want a specific kind of float, e.g. 4.0f0 or 4.0d0

beach: not sure. I worked mostly with Ahmon and Kevin. Andreas came on board then took off to stripe while I was there.
