Ok, cancel question #3.   I now realize it's an error to call even?,
odd?, fleven?, or flodd? with an inexact number not representing an
integer value.

But add the following,

"
fl-log2-e

Bound to the value of (fllog fl-e 2.0). (C99 M_LOG2E)

fl-log10-e

Bound to the value of (fllog fl-e 10.0). (C99 M_LOG10E)
"

fllog is not specified to take 2 arguments.   Should it?  Or should
these references to be fllog2 and fllog10 respectively?
