12:32 PM seb_kuzminsky: these are all expected to fail, it's a new test that identifies a bug in the new limit3 that zultron's working on

06:15 PM andypugh: Do we have a routine anywhere in the code that can be used to compare floats?
06:37 PM skunkworks: for what? like http://linuxcnc.org/docs/2.7/html/man/man9/comp.9.html
06:39 PM andypugh: Ah, no. I want to compare two floats for equality in the smart-serial code to see if the value has ben changed.
06:40 PM andypugh: And it’s harder than you might think. Especially as the value is stored as a double in HAL, but could be any number of bits when transmitted through smart-serial (including, potentially, quarter-precision)
06:42 PM skunkworks: sure - comparing floating point numbers can be a pain
06:45 PM andypugh: I think that the right way to do it might be to store them in a union with a u64, shift them right until only the specified number of bits show, subtract them and see if the result > 2
06:54 PM andypugh: No, that doesn’t actually work.
06:56 PM andypugh: jepler: Any ideas? I read an article on it, and that seemed fairly happy with looking at the difference between integer representations, but it gets harder when you have to consider that the value in the double might have come from a float.
07:14 PM andypugh: Who has the boot for #linuxcnc?
07:16 PM sync: seems like freenode has some pranksters again
07:16 PM sync: my box was ddosed off the interwebs this morning
07:17 PM sync: ah
07:17 PM sync: it is LRH spam
07:17 PM sync: well
09:38 PM jepler: have a libssl update everyone. bouncing the forum to make sure it takes effect.
09:38 PM jepler: er, hm, debian has an update but ubuntu lts doesn't yet.
09:39 PM jepler: oh, maybe it was in an earlier update I ran on forum. all's well.
