1. the concept that Maxima fails to "preserve precision" that seems to be bandied about here doesn't seem to me to make much sense. You have 2 numbers of different precisions and you operate on them. What is supposed to be preserved? 2. If the MPFR fraction has N bits, then ?fpprec:N will b

I just turned off experimental. There aren't that many things being tested there at the moment, so no one should need to use it. One of plugins being tested (the git plugin) may also be causing all of these zombie git processes. On Thu, Jun 14, 2012 at 2:14 PM, Jonathan Bober wrote: > I think th

If you did this you'd need to tell maxima to assume various things about the variables (real, in between floatvalue - epsilon and floatvalue + epsilon...). I don't know maxima well enough to determine how feasible this idea is if you made such assumptions, but it's worth investigating. David On T
