Under Ultrix 3.0 on a DECstation 3100, the following script files
shows that ldexp() incorrectly scales the value 0.0. Is this
still true under 3.1? Could someone else verify this for me?
Thanks! (I know ldexp() works properly under the uVAXen versions
of Ultrix, but am curious as to whether it's been fixed in 3.1.)
