I've heard that ARM processors work best with Fixed Point math. The game library Allegro has many fixed point functions and I would like to know if PPL has any. From the research I've done, creating a fixed point library isn't a trivial task. Would fixed point math speed up operations in PPL? Thank you for your consideration. | ||

Is this version still coming or will I have to wait for 2.0. Also, should I buy 1.5xxx now or wait for 2.0. From the April newsletter I know no price is set in stone but I would like to know which option makes more sense. Thanks. (Sorry if there was a double post.) | ||

PPL 1.52 will be coming out soon, there will be an upgrade fee for PPL 2.0 for all PPL 1.x customers. No prices have been announced yet.
