Post by thread:Floating Point in PIC18f

Hi, How do i represent Floating Point numbers in PIC? I've tried to googled it but came up with nothing. If I used Floating point, does all the instruction for add,subtract,compare function still applicable? Thanks in advance. From - wan -- http://www.piclist.com#nomail Going offline?

I also suggest you check out the Microchip application notes on floating point: http://tinyurl.com/6gq7y > If I used Floating point, does all the instruction for > add,subtract,compare function still applicable?

A suggestion: instead of asking what can be done, describe what you are trying to do. Anything can be done in software. The question is what needs to be done. For example if the range and precision are well known, it may be possible to do it with fixed point format. But without knowing the application it's hard to make a determination. Also high level languages often support floating point. For example Sergio's XCSB has floating point support. You can find a Lite version of it here: http://xcprod.com/titan/XCSB So tell us what you're trying to do, and then maybe you can get a better suggestion of how to accomplish it with the limited resources available.
