21:10:11mfianoAlways found CLISP's arbitrary precision floats strange, in regard to the constant value pi. IIRC, the manual even says that it is no longer a constant value, which seems wrong to me.
21:12:03_deathwell, it's an approximation after all
21:12:54Nilby_death: Yes, but I'm not that pleased with clisp anymore, and I haven't used sb-mpfr because I worry about implementation in C and possible overhead.
21:17:06_deathI never found actual use for them.. for floating point, I'm fine with single and double precision.. and sometimes I need to move to a fixed point or maintain my own scaling or use rationals (slow..) or logarithms solve the issue.. but not arbitrary precision floats
21:21:50NilbyI love how close to mathematically correct Lisp math is relative to other languages, but it starts getting corrupt with floating point error. I've be gravely injured before (in virtual realites) by floating point error.
