I'm not sure I understand the question. Floating point numbers are bits in memory, just like any other data. Disk and tape and similar data storage device I/O just moves memory words to/from the device; it doesn't matter what the bit patterns mean. Data interpretation does matter for output to devices like line printers, of course; printing a decimal nummber is different for float vs. integer. paul
