But I think Erlang ought to have support for doing it (as well as sensible defaults). You should be able to (1) compliantly detect and work with all the various special IEEE fp values and classes in Erlang, and you should be able to (2) manage the various
flags that control IEEE fp behaviour, again in Erlang and probably also on the command line.</span></font></div><div style="color: rgb(0, 0, 0); font-size: 13px; background-color: transparent; font-style: normal; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;"><font><br class="" style=""></font></div><div style="color: rgb(0, 0, 0); font-size: 13px; background-color: transparent; font-style: normal; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;"><font>Here's what CMU Common Lisp does about floats: <a href="http://www.umiacs.umd.edu/~resnik/ling645_sp2002/cmu_manual/node15.html" class="" style="">http://www.umiacs.umd.edu/~resnik/ling645_sp2002/cmu_manual/node15.html</a></font></div><div style="color: rgb(0, 0, 0); font-size: 13px; background-color: transparent; font-style: normal; font-family: HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida
