My mistake.  I thought it returned #f when I checkked.  But, then what
about:

guile> (define b (/ 1 0))
guile> b
+#.#
guile> (inexact? b)
#t
guile> (inexact->exact b)
ERROR: In procedure inexact->exact in expression (inexact->exact b):
ERROR: Wrong type argument in position 1: +#.#
ABORT: (wrong-type-arg)
