@@Andrewman For most graphing calculator uses, you don't need the precision of a 64 bit floating point number. The only advantage x64 provides is more RAM that can be used.

The biggest advantage with ARM specifically is the multithreading capabilities, but I have no clue how you'd divide the calculation of a single function. Maybe one thread per graph rendered in a moving thing like this. Anyways, those little optimizations are probably for extreme use-cases. But what I do know is that x86 won't go away.

(Also, if you pause at the right times, sometimes you'll be able to see slight horizontal asymmetries in the shapes, which can't happen with ellipses) EDIT: The reason they are so similar probably has to do with how the positive part of a sine wave looks like a parabola, which is a degree-2 algebraic curve.
