IEEE NaN and Infinities

I am fiddling around with IEEE NaN and Infinities.
In LW and CCL you have the following conventions for such things:
1d+-0 is NaN (quiet; double float)
1d++0 is positive infinity (double float)
Negative infinities are obtained by prepending ‘-‘ to the positive infinities. Other float lengths can be obtained by using the appropriate ’s’, ‘e’, ‘f’, ‘l’.
I tried an (APROPOS “NAN”) and an (APROPOS “INFINITY”) in ABCL, but got nothing.
Being myself a lazy bastard, I thought of asking directly here instead of looking at the code :) Any possibility of seeing these in ABCL?
Apart from that, there is the issue of “rounding modes”. Would it be possible to add them or access them in ABCL?
