I am programming in LSC.  I want to do floating point arithmetic as fast as
possible on a machine with a floating point chip, but have the program still
run (slower) on a plain Mac.  How do I do that?  How do I determine if I am
executing on a machine with floating point?

Even if the answer is that a floating point expression in LSC is automatically
executed with the floating point package, which invokes SANE,
which invokes the floating point chip if it is present, is there
a faster way? I.e. can I bypass the floating point package and
SANE to get faster execution?
