The algorithm only works with points with integer coordinates, so the slope is always rational.

- FredBrach 14y agoI think you have the last words because line drawing algorithms become irrelevant if you use a Floating Point Unit. just: { x++ and y+=slope } or { y++ and x+= 1./slope } Then slopes are always rational in line drawing algorithms.
- ralph 14y agoIf y and slope are floating point in the first block then might not y end at other than the desired endpoint because of accumulative error?
