OK, that's a bit confusing -- we have SCM_COMPLEXP which does *not* mean the same thing as scm_complex_p -- the former checks to make sure the object, tag-wise, is a complex smob, the latter checks to see if the object actually contains a complex number, so we have (complex? 3) -> #t but SCM_COMPLEX(SCM_MKINUM(3)) -> 0 -- Rob Browning rlb @defaultvalue.org, @linuxdevel.com, and @debian.org Previously @cs.utexas.edu GPG=1C58 8B2C FB5E 3F64 EA5C 64AE 78FE E5FE F0CB A0AD _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://mail.gnu.org/mailman/listinfo/guile-devel
