Negative coordinate affect on Allegro performance?

A new Open Compute spec (DC-MHS) places the origin for the PCB in the 'upper left' corner and makes the vast majority of the board have negative coordinates.

In the past, handling negative number could drastically decrease the performance of a program.

Would Allegro require more computation to handle negative coordinates vs. positive coordinates? Or does the newer CPUs with larger instruction sets and more floating point capability resolve this concern?

I don't believe negative coordinates make a difference.

My designs tend to have the origin set as center of the entire board. Leaving the origin where mechanical engineers defined it in their assembly avoids angry hate mail if I forget to move it back before giving them a step assembly to put in their model.
