I need to match print ads sizes from various publications with a standardized list of ratios (e.g. 2:1, 1:1, 2:7...) plus a bunch of other metrics.

So ��a rect of 1543@331 gives a float value that has can be best approximated by a continued fraction approach.

But there are other complications. Now I am using a lookup table and try to match with just a distance.

I am using DataFrame and hopefully more Roassal for all of this.

Pharo can be a good tool to manage the object model of this problem space. I am prototyping something. We'll see how far I can get.

Hi phil

just out of sane curiosity do you have a pointer on ratio and
rectangle and continued fraction?
