the webpage of mike predko, http://www.myke.com/picmicro/16bit.htm contains some 16 bit operations which seem to fit the bill. I cannot vouch for them personally since I'm only just starting out.

Dear piclisters,

Does anyone have a full collection of TESTED 16 bit (unsigned) math
routines?
I am looking for:

16bit add
16bit subtract
16bit*16bit multiply (32bit result)
32bit/16 bit divide (16bit quotient+16bit remainder)
plus maybe:
16bit/8bit divide

Microchip has some math macros, but I know they are buggy.

Thanks,
Mark Langezaal
