I have a server program that is sending a block of data that
has binary encoded data. I have written some Java code that
can take the array of bytes and parse it back to Java ints
(using b1+256*b2+512*b3+1024*b4) and Strings. The server is
sending floats as 4 bytes in IEEE format which is supposed to
be compatible with Java floats. The problem is that I have
found NO library calls which will convert 4 bytes into a float
(and vica versa). This is easy in C/C++ by playing with pointers,
but Java won't (correct me if I'm wrong) cast a array of bytes
to a float (or vica versa). I could cheat and do this with
native methods, but that would'nt solve this problem elegantly.
Does anyone know of a way to do this? How is the Datastream.readFloat()
implemented in the source?
Thanks in advance
