Converting Byte Arrays [message #10049]

I am struggling with a file i/o problem. I have a data file which comes
from a PC. I know the data structure in terms of how many bytes correspond
to each entry in the file and what file type for each of these entries
(i.e. integer, real, etc). Generally, I two bytes into a variable for a
integer and 4 bytes for a real. I can convert the integers simply enough.
For a variable named id which is a bytarr(2) the integer is simply
256*id(1)+id(0). However, how can I convert the 4 byte arrays which are
floats into the proper numbers? I seem to come up with gibberish if I do a
simple float(val) where val=byytarr(4).

Any thoughts or tricks? All help much appreciated.
