Fast Integer Division
PostPosted: Mon Apr 19, 2004 11:01 am     Reply with quote

Hi
Is there any way of dividing two 16bit integers, a and b (where a<b and b != 0) without recieving a floating point number but instead a fraction with a denominator of 2^16. Something similar to motorola's FDIV. I'm using an 18f6720. (i couldn't find anything on other posts but maybe i missed something...)
Thanks

x=a/b

is the same as

x*2^16=(a*2^16)/b

To do this you must perform 32 bit division. I don't know what it benifit's you but it will work.
