IEEE NaN and Infinities

[Antoniotti Marco]

Hi

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?

Thanks

Marco
