Hi everyone,

I've been using ieee-floats for a bit more than a year now and I'm very
happy with it: its simple to use and fast (see an example in function
"mk-mts-from-double" in the following file
https://raw.github.com/christophe-pouzat/Neuronal-spike-sorting/master/code/spike-sorting.lisp;
the example is with 64-bit data but it works immediately with 32-bit
data with obvious changes). There is a function doing the same job in
GSLL (I forgot the name, sorry) but it's at least an order of magnitude
slower.

Programming languages teach you not to want what they cannot provide.  You have to think in a language to write programs in it, and it's hard to want something you can't describe.
