numeric tests

[Bill Schottstaedt]

Out of mild curiousity, I translated some of Clisp's numerical tests
(released under GPL in Clisp, so presumably this is ok) to Scheme
using the "pass-if" style of Guile's tests, and noticed some odd
cases.  I spot-checked some of the worst looking results in
gmp-3.0.1's pexpr program which agreed with Clisp (i.e. that the test
should return 0).  For example, test 313, guile=8192.0, 335 got 5+e123
etc.  In case there's interest (some of the tests are a bit nutty),
the file is at ccrma-ftp.stanford.edu/pub/Lisp/number-tests.scm.
