I don't think you understand what I'm saying. When you get a Java program,
it's in bits and bytes, including all the fp numbers already in ieee
Or are you saying that you will port the Java compiler and JVM, and only
be able to run those Java programs that you yourself will write and
compile on your compiler?
Why on earth in that case? C++ should work just as well for you.
