12:28 <mwnaylor> bremner: Just got back to erc. Yes, cider is the Clojure repl tool. Links lein repl. Tight intergration w/ source. Compile source, definfinitions available in the namespace. Autocompletion for values & functions, etc.

13:28 <mwnaylor> Woohoo!!!! I just hacked (in the good sense) part of the geiser source to get rid of an error caused by an obsolete function. Now I can get documentation in geiser-racket!!

17:03 <mjt128> has anyone ever tried to implement the common lisp condition system in racket?

21:58 <orylesor> Hi. I'm Teresa. (she/her)

21:58 <orylesor> I was just wondering what the cube root of -8 was. I tried `(expt -8 1/3)`. It evaluated to `1.0+1.732050807568877i`. My girlfriend says that it should be just 2. Where did I go wrong?

22:09 <bremner> orylesor: I think racket is (close to) correct. Try cubing that complex number

22:11 <orylesor> bremner: I just tried it. `(expt (expt -8 1/3) 3)` evaluated to `-7.999999999999995+9.79717439317882e-16i`. Does this check out?

22:12 <bremner> yeah, given floating point error, that is very close to -8

22:13 <orylesor> This is exactly what I wished to know. Appreciate it! Have a relaxing weekend.

22:13 <bremner> welcome

23:29 <ampersam> Hi, I'm Prof. Richard Holder (vi/vim) at the University of Northern South Dakota. Allow me to explain, its quite complex. Y is the cube root of X when Y * Y * Y = X. I posited this to my rentboy, who is not a mathematician by trade, and he seemed to take this hard concept into himself freely. I believe this is a good place to begin, as we've turned a cube root into elementary multiplication. Now,

23:29 <ampersam> lets posit negative X, I'm positive that you know negative numbers else the negation of my positive views of the primary education system. In this scenario, -2 would be teh cube route of -8, as -2 * -2 * -2 simplifies to 4 * -2 which is -8. I do believe there is a problem with your installation of Racket as your answer is positive. No matter how many repetitions to the point ad nausoleum one will

23:29 <ampersam> multiply a postive number, the answer may never become negative. At least, not in our lifetime, as The Bible's header file defines our physical universe's MAXINT as something quite large, large enough to contain all atoms on a beach of sand, obviously one cannot overflow physical reality easily or our universe would not function. Thank you for reading orylesor.
