Hello PIC.ers, I use the windows ms calculator a lot, for hex <> binary <> dec conversions and direct calculations in the bases without having to rigmarole (through eg base10) to get a hex multiply or divide done. Well & good, the help file says it operates out to 32 digits, but this seems to only apply to decimal, not hex. which saturates at 6 digits (= 24bits). Has anyone figured out how to get the thing to go further? I want to do 64bit or 8 hex. byte calcs. best regards, John e-mail from the desk of John Sanderson, JS Controls.
