I have a rather peculiar problem for which I do not know if there is a solution.
I am reading a 16-bit floating point number from an HDF file using IDL's built in HDF commands. This number, of course, is typed to be a 32-bit floating point number by IDL. The problem is that this number was originally two 1-byte integers, which were stuffed together into one 16-bit field in a C program. (Don't ask why that was done.)
I need to reverse engineer the 32-bit floating point number to recall the original two 1-byte integers.
Does anyone know how (or if) this can be done?
Thanks,
Brian
