Would the following be okay - and correct? ----------------------------------------------------------------- Clisp ----- Clisp includes GNU readline support, so Maxima has advanced command-line editing facilities when built with it. Clisp is compiled to bytecodes, so Maxima running on Clisp is substantially slower than on Lisps compiled to machine instructions. On the other hand, Clisp contains code from CLN (link to http://www.ginac.de/CLN/), a library for efficient computations with all kinds of numbers in arbitrary precision. Clisp is very portable, there are Clisp implementations for many platforms including MS Windows and Unix-like systems. ------------------------------------------------------------------ > Does maxima use long-float and if yes, does it use (setf > ext:long-float-digits) to set the wanted precision (possibly big)? I do not know very much about Maxima's internals, sorry. > If it only uses single-float and double-float, then it's done in > hardware. One can use double precision and arbitrary precision floats: (%i1) sqrt(2),numer; /* compute sqrt(2) numerically as double */ (%o1) 1.414213562373095 (%i2) fpprec:60$ /* set the precision for bloats to 60 digits */ (%i3) bfloat(sqrt(2)); /* compute sqrt(2) as a bigfloat (bfloat) */ (%o3) 1.41421356237309504880168872420969807856967187537694807317668b0 I assume, that the first may be done in hardware. But as Jörg pointed out, the bytecode of calculating large expressions may be slow. Thanks for all the answers and very fine, that Clisp development is going on. Best regards, Wolfgang (Is there a way, that Clisp may produce machine code instead of bytecode, to speed it up? There seem to be the possibility to use a just-in-time-compiler (lightning) - does that work? If so, perhaps one of the next releases may have enabled it by default?) ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
