> The example where computing an expression with posits has much better accuracy than when computing with IEEE FP32 is extremely misleading.

Did you not rtfa or am I missing something?

practically speaking we did put this to the test by having someone run a fluid dynamics simulation on fp64 vs posit64 vs posit32 with no algorithm changes (using fp128 as a "ground truth").

unsurprisingly posit64 results were closer to fp128 than fp64.
