[sci.math] Algorithm for 32 bit arithmetic on 8 bit machine

ellis@motcid.UUCP (John T Ellis) (01/29/91)

A question for the math/cs gurus out there.  I'm working on an 8 bit machine
but have run into the situation where I need 32 bit arithmetic ie mulitply and
divide.  I know the "largest" number I could ever receive from applying an operation is 31 bits.  

Is there anyone who has an algorithm, some insights into how to best accomplish
this, or leads on literature?  I'm sure I could figure it out, but I would 
rather not reinvent the wheel.

If there is interest, I will post a summary of responses.

Thanks.
